scsi: lpfc: do not set queue->page_count to 0 if pc_sli4_params.wqpcnt is invalid
commit 4e87eb2f46ea547d12a276b2e696ab934d16cfb6 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.
Fixes: 895427bd01 ("scsi: lpfc: NVME Initiator: Base modifications")
