[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.
