Eliad Peller af390f4dd3 wlcore: protect wlcore_op_set_key with mutex
wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.

Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.

Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

[Arik - move state != ON check]

Yair Shapira e166de556f wl18xx: number_of_assembled_ant5 indicates if A band is enabled
Use number_of_assembled_ant5 phy param to indicate if A band is enabled:
if number_of_assembled_ant5 != 0 then it is enabled otherwise it is
disabled.

This aligns with phy implementation that uses this param both to indicate
if band is active and the number of antennas.

This parameter replaces enable_11a module param that was removed.

User-Space applications can use wlconf and/or INI files to disable A band
using this parameter.

Ido Yariv 4cc533830b wlcore: Prevent interaction with HW after recovery is queued
When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.
