Wanpeng Li 6713c3aa7f sched: Remove superfluous resetting of the p->dl_throttled flag 
Resetting the p->dl_throttled flag in rt_mutex_setprio() (for a task that is going
to be boosted) is superfluous, as the natural place to do so is in
replenish_dl_entity().

If the task was on the runqueue and it is boosted by a DL task, it will be enqueued
back with ENQUEUE_REPLENISH flag set, which can guarantee that dl_throttled is
reset in replenish_dl_entity().

This patch drops the resetting of throttled status in function rt_mutex_setprio().
