Stray reference to RQF_SORTED

Hi Jens,

In commit a1ce35fa49852db60fc6e268038530be533c5b15 ("block: remove dead
elevator code") you removed all users of RQF_SORTED. However there is
still one reference left to it:

block/blk-mq-sched.c:412:               rq->rq_flags |= RQF_SORTED;

This in effect is dead code now. Should this statement have been
removed as part of the aforementioned commit? And then maybe also the
definition of RQF_SORTED, to prevent further confusion?

Thanks,
