sched: move the __update_rq_clock() call to scheduler_tick()
move the __update_rq_clock() call from update_cpu_load() to scheduler_tick(). ( identity transformation that causes no change in functionality. ) this allows the direct use of rq->clock in ->task_tick() functions. Signed-off-by: Ingo Molnar <mingo@elte.hu>
