scsi: qla2xxx: Fix recursive mailbox timeout
[ Upstream commit 710bc78f829d014eca95ed7ccc4052bc064b1320 ]
This patch prevents user space mailbox request from doing chip reset if the
mailbox timed out. The chip reset is only reserved for the DPC thread to
ensure all mailbox requests are flushed properly. The DPC thread is
responsible for the flushing all MBs and chip reset.
