If the VF driver fails to complete early init, then rmmod can cause a

Add a check to see if the timer is actually initialized before stopping

FW can indicate any admin queue error states to the driver via some bits
in the length registers. Each time we process an admin queue message,
check these bits and log any errors we find. Since the VF really can't
do much, we just print the message and depend on the PF driver to clear
things up on our behalf.

i40evf_set_ringparam was broken in several ways. First, it only changed
the size of the first ring, and second, changing the ring size would
often result in a panic because it would change the count before
deallocating resources, causing the driver to either free nonexistent
buffers, or leak leftover buffers.
Fix this by storing the descriptor count in the adapter structure, and
updating the count for each ring each time we allocate them. This
ensures that we always free the right size ring, and always end up with
the requested count when the device is (re)opened.

On the other hand, a reinit is no big deal and we can use the admin

This fixes a Tx hang and FW crash that happens after setting the MTU on

Respond better to a VF reset event. When a reset is signaled by the
PF, or detected by the watchdog task, prevent the watchdog from
processing admin queue requests, and schedule the reset task.
In the reset task, wait first for the reset to start, then for it to
complete, then reinit the driver.
If the reset never appears to complete after a long, long time (>10
seconds is possible depending on what's going on with the PF driver),
then set a flag to indicate that PF communications have failed.
If this flag is set, check for the reset to complete in the watchdog,
and attempt to do a full reinitialization of the driver from scratch.
With these changes the VF driver correctly handles a PF reset event
while running on bare metal, or in a VM.
