Request list is determined by blk_get_rl() and without queue_lock.

This code is going away shortly, so let's just leave the comment
alone.


Ok, I see some patches in flight for 420

Probably they also fixes linking non-bio based request with cgroups?
I've found that old stack calls blk_rq_set_rl() for all request
while MQ do this only in blk_mq_bio_to_request,
in blk_mq_get_request() request gets only io-context.
