[SCSI] qla1280: eliminate wasted space in request and response ring

i think there is wasted space in allocated pages for request and
response rings.  The allocations are made with REQUEST_ENTRY_CNT + 1
and RESPONSE_ENTRY_CNT + 1, but they are set with 256 and 16.

So we got more pages, which we dont use very much so eliminate them.
