scsi: lpfc: do not set queue->page_count to 0 if pc_sli4_params.wqpcnt is invalid
commit 4e87eb2f upstream. Certain older adapters such as the OneConnect OCe10100 may not have a valid wqpcnt value. In this case, do not set queue->page_count to 0 in lpfc_sli4_queue_alloc() as this will prevent the driver from initializing.
