qla2xxx: Move atioq to a different lock to reduce lock contention
99% of the time the ATIOQ has SCSI command. The other 1% of time
is something else. Most of the time this interrupt does not need
to hold the hardware_lock. We're moving the ATIO interrupt thread
to a different lock to reduce lock contention.
