Convert blk-ioprio handling from a rqos policy to a direct call from blk_mq_submit_bio(). Firstly, blk-ioprio is not much of a rqos policy anyway, it just needs a hook in bio submission path to set the bio's IO priority. Secondly, the rqos .track hook gets actually called too late for blk-ioprio purposes and introducing a special rqos hook just for blk-ioprio looks even weirder.
