Hi Jens,

The two patches fixes boot hang issue in lots of test vm system.
And the cause is in blk_mq_tagset_busy_iter().

V2:
	- move blk_mq_request_started() into header file as suggested by
	  James

I'd be fine with moving that into a header, if the target of this
was 4.19. But it's not, so there's absolutely no point to include
that in this series.

I'm going to apply 2/2 for 4.18.
