The FC-GS-3 sepc requires to wait for least 3 times R_A_TOV per
sec 4.6.1 "If the Requesting_CT does not receive a Response
CT_IU from the Responding_CT within three times R_A_TOV,
it shall consider this to be a protocol error."
This means added four new states with management server
could add significant delay with multiple retries
on default 12 second timeout(3 * R_A_TOV), so instead
just skip these states on very first timeout on any of
these states to not stuck with states for such longer
period.

Noticed that we can shuffle the code around in fcoe_percpu_receive_thread a bit
and avoid taking the fcoe_rx_list lock twice per iteration. This should improve
throughput somewhat. With this change we take the lock, and check for new
frames in a single critical section. Only if the list is empty do we drop the
lock and re-acquire it after being signaled to wake up.
Change Notes:
v2) did some further cleanup on the patch by replacing the 2nd call of
spin_lock/splice_init with a goto to the top of the outer loop. This allows me
to change the inner while loop to an if conditional and remove the sencond check
of kthread_should_stop. Based on suggestion from Vasu Dev.

This patch fixes the following Coverity reported warning:

commit 198439e4 [SCSI] libsas: do not set res = 0 in sas_ex_discover_dev()

The above commits seem to have confused the return value of
sas_ex_discover_dev which is non-zero on failure and
sas_ex_join_wide_port which just indicates short circuiting discovery on
already established ports. The result is random discovery failures
depending on configuration.
Calls to sas_ex_join_wide_port are the source of the trouble as its
return value is errantly assigned to 'res'. Convert it to bool and stop
returning its result up the stack.

Rapid ata hotplug on a libsas controller results in cases where libsas
is waiting indefinitely on eh to perform an ata probe.
A race exists between scsi_schedule_eh() and scsi_restart_operations()
in the case when scsi_restart_operations() issues i/o to other devices
in the sas domain. When this happens the host state transitions from
SHOST_RECOVERY (set by scsi_schedule_eh) back to SHOST_RUNNING and
->host_busy is non-zero so we put the eh thread to sleep even though
->host_eh_scheduled is active.
Before putting the error handler to sleep we need to check if the
host_state needs to return to SHOST_RECOVERY for another trip through
eh. Since i/o that is released by scsi_restart_operations has been
blocked for at least one eh cycle, this implementation allows those
i/o's to run before another eh cycle starts to discourage hung task
timeouts.

When managing shost->host_eh_scheduled libata assumes that there is a
1:1 shost-to-ata_port relationship. libsas creates a 1:N relationship
so it needs to manage host_eh_scheduled cumulatively at the host level.
The sched_eh and end_eh port port ops allow libsas to track when domain
devices enter/leave the "eh-pending" state under ha->lock (previously
named ha->state_lock, but it is no longer just a lock for ha->state
changes).
Since host_eh_scheduled indicates eh without backing commands pinning
the device it can be deallocated at any time. Move the taking of the
domain_device reference under the port_lock to guarantee that the
ata_port stays around for the duration of eh.

- Remove the queue dead check from scsi_run_queue() since the

where the queue lock is not held.
- Remove the queue dead check from the start of scsi_request_fn()
