If ibmvfc_init_sub_crqs() fails ibmvfc_probe() simply parrots registration failure reported elsewhere, and futher vhost->scsi_scrq.scrq == NULL is indication enough to the driver that it has no sub-CRQs available. The mq_enabled check can also be moved into ibmvfc_init_sub_crqs() such that each caller doesn't have to gate the call with a mq_enabled check. Finally, in the case of sub-CRQ setup failure setting do_enquiry can be turned off to putting the driver into single queue fallback mode. The aforementioned changes also simplify the next patch in the series that fixes a hard reset issue, by tying a sub-CRQ setup failure and do_enquiry logic into ibmvfc_init_sub_crqs().
