block: remove unnecessary argument from blk_execute_rq_nowait 

The 'q' is not used since commit a1ce35fa49 ("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.
