[PATCH] sched/deadline: Replace rq_of_dl_rq(dl_rq_of_se(dl_se)) with ... ...task_rq(dl_task_of(dl_se))

[Qi Zheng <arch0.zheng@gmail.com>]

The rq is already obtained in the dl_rq_of_se() function:
	struct task_struct *p = dl_task_of(dl_se);
        struct rq *rq = task_rq(p);
So there is no need to do extra conversion.
