This in preparation to retire blk_mq_pci_map_queues. For his_sas_v2_hw.c we have to provide its own callback for retrieving the affinity because pci_get_blk_mq_affinity is using pci_irq_get_affinity and not irq_data_get_affinity_mask. But at least we can replace the open code loop with blk_mq_hctx_map_queues.
