We should not need multiple submission queues for IRQ steering.

We just need to build the cpu to vector reverse map that
blk_mq_pci_map_queues builds.  So maybe we need to refactor
the API for ->map_queues a bit so that it's not tied to
submission queues.  In the meantime you can just opencode
that loop.
