[PATCH 6/7] sched/deadline: depend on clearing throttled status in replenish_dl_entity

[Wanpeng Li]

Since the natural place to clear ->dl_throttled is in replenish_dl_entity(), and 
the task which is adjusted the priority is the current, it will be dequeued and 
then enqueued w/ replenish which can guarantee ->dl_throttled can be cleared, 
this patch drop the clear throttled status in function rt_mutex_setprio.
