[PATCH 1/1] sched: Add update_rq_clock() in sched_rt_rq_enqueue()

[YT Chang]

Add update_rq_clock() in sched_rt_rq_enqueue() to
prevent the warning "rq->clock_update_flags < RQCF_ACT_SKIP"
when call rq_clock() in cpufreq_update_util().

sched_rt_rq_enqueue ->
   enqueue_top_rt_rq ->
      cpufreq_update_util ->
         rq_clock ->
            assert_clock_updated
