[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.
