[PATCH v2 3/6] scsi: hisi_sas: replace blk_mq_pci_map_queues with blk_mq_hctx_map_queues

[Daniel Wagner]

From: Daniel Wagner <dwagner at suse.de>

Replace all users of blk_mq_pci_map_queues with the more generic
blk_mq_hctx_map_queues. This in preparation to retire
blk_mq_pci_map_queues.

For his_sas_v2_hw.c needs its own callback for retrieving the affinity.
The generic bus_type get queue affinity callback is using
pci_irq_get_affinity and not irq_data_get_affinity_mask.

This allows it to replace the open code loop with
blk_mq_hctx_map_queues at least.
