snic: Fix for missing interrupts
- On posting an IO to the firmware, adapter generates an interrupt.
Due to hardware issues, sometimes the adapter fails to generate
the interrupt. This behavior skips updating transmit queue-
counters, which in turn causes the queue full condition. The fix
addresses the queue full condition.
- The fix also reserves a slot in transmit queue for hba reset.
when queue full is observed during IO, there will always be room
to post hba reset command.
