Merge three functions only tail-called by blk_mq_free_request into
blk_mq_free_request.

This doesn't compile, as blk_mq_merge_queue_io() has a call to
__blk_mq_finish_request().

Hmm.  The tree I've based my work on certainly doesn't.  But it doesn't
even have blk_mq_merge_queue_io at all either, as does your for-4.13/block
block tree.

What am I missing?
