[PATCH V3 05/10] nvme: replace blk_mq_pci_map_queues with blk_mq_dev_map_queues

[Ming Lei]

Replace blk_mq_pci_map_queues with blk_mq_dev_map_queues which is more
generic from blk-mq viewpoint, so we can unify all map queue via
blk_mq_dev_map_queues().

Meantime we can pass 'use_manage_irq' info to blk-mq via
blk_mq_dev_map_queues(), this info needn't be 100% accurate, and what
we need is that true has to be passed in if the hba really uses managed
irq.
