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.
