The poll code is blk-mq specific, let's move it to blk-mq.c. This
is a prep patch for improving the polling code.

So I gave my ok earlier, but I spent some more time looking at this
this morning and now I wonder why we even bother to keep some
code in blk-core.c. How about just renaming the whole damn thing
to blk_mq_poll and move it to blk-mq.c instead of that split?

I pondered that too, and I guess we might as well since the likelihood
of supporting polling on non-mq is pretty close to 0%.
