[SCSI] qla2xxx: Remove interrupt request bit check in the response processing path in multiq mode.

Correct response-queue-0 processing by instructing the firmware
to run with interrupt-handshaking disabled, similarly to what is
now done for all non-0 response queues.  Since all
response-queues now run in the same mode, the driver no longer
needs the hot-path 'is-disabled-HCCR' test.
