blk-throttle: Move service tree validation out of the throtl_rb_first()
The throtl_schedule_next_dispatch() will validate if the service queue
is empty before calling update_min_dispatch_time(), and the
update_min_dispatch_time() will call throtl_rb_first(), which will
validate service queue again.
Thus we can move the service queue validation out of the
throtl_rb_first() to remove the redundant validation in the fast path.
