In case of q->elevator, passthrough request can still be marked as
RQF_ELV, so some elevator callbacks will be called for them.
Fix this by splitting RQF_SCHED_TAGS, which is set for all requests that
are issued on a queue that uses an I/O scheduler, and RQF_USE_SCHED for
non-flush, non-passthrough requests on such a queue.
Roughly based on two different patches from
Ming Lei <ming.lei@redhat.com>.
