sched: fix goto retry in pick_next_task_rt()
looking at it one more time: (1) it looks to me that there is no need to call sched_rt_ratio_exceeded() from pick_next_rt_entity() - [ for CONFIG_FAIR_GROUP_SCHED ] queues with rt_rq->rt_throttled are not within this 'tree-like hierarchy' (or whatever we should call it :-) - there is also no need to re-check 'rt_rq->rt_time > ratio' at this point as 'rt_rq->rt_time' couldn't have been increased since the last call to update_curr_rt() (which obviously calls sched_rt_ratio_esceeded()) well, it might be that 'ratio' for this rt_rq has been re-configured (and the period over which this rt_rq was active has not yet been finished)... but I don't think we should really take this into account. (2) now pick_next_rt_entity() must never return NULL, so let's change pick_next_task_rt() accordingly.
