[SCSI] qla2xxx: Reduce request queue-size overhead with recent ISPs.
The original code to 'resize request-queues' based on iocb-counts
and employed during early ISP23xx testing was too
overly-pessimistic with regards to latencies in the firmware
pulling requests. Recent ISPs can easily keep up processing a
stream of commands from an abbreviated (effectively, half the
original size) queue.
