We store a ->rq_disk in struct request, so we should also not need
that.  And at_head should either become a bool, or be replaced with
a flags argument, ints used boolean are usually not a good idea.

And all the same argument changes that apply to blk_execute_rq_nowait
apply to blk_execute_rq as well.
