The 'q' is not used since commit a1ce35fa4985 ("block: remove dead
elevator code"), also update the comment of the function.
And more importantly it never really was needed to start with given
that we can trivial derive it from struct request.

We can remove 'q' from blk_execute_rq as well after the previous change
in blk_execute_rq_nowait.
And more importantly it never really was needed to start with given
that we can trivial derive it from struct request.
