[PATCH v2 3/6] block: loop: convert to blk-mq

The conversion is a bit straightforward, and use per-hw_queue kthread work queue to dispatch reqests of loop block, so scalability gets improved a lot if nr_hw_queues is increased. Another benefit is that loop driver code gets simplified much, and the patch can be thought as cleanup too. Signed-o
