blk_mq_alloc_request_hctx() allocates a driver request directly, unlike
its blk_mq_alloc_request() counterpart. It also crashes because it
doesn't update the tags->rqs map.
Fix it by making it allocate a scheduler request.

I think this should do it. Verified that normal operation still works
for me, but I'm not sure how to test the actual _hctx() alloc path.
Sagi, could you please test this series out?
Hm, Sagi, your mail server seems to have rejected patches 2 and 3
because git-send-email duplicated the in-reply-to header for some
reason. I've attached the patches instead.
Strange, I got the them.
