block: skip q->rq_qos check in rq_qos_done_bio()
[ Upstream commit 275332877e2fa9d6efa7402b1e897f6c6ee695bb ]
If a bio has BIO_QOS_THROTTLED or BIO_QOS_MERGED set,
it implicitly guarantees that q->rq_qos is present.
Avoid re-checking q->rq_qos in this case and call
__rq_qos_done_bio() directly as a minor optimization.
