[PATCH] sched/rt: Fix a comment in pick_next_task_rt()

From: Muchun Song
Date: Fri Oct 26 2018 - 23:05:40 EST

Commit f4ebcbc0d7e0 ("sched/rt: Substract number of tasks of throttled
queues from rq->nr_running") added a new member rt_rq->rt_queued, which
is used to indicate the status of rq->rt enqueue or dequeue. So, the
check rt_nr_running was removed and we now check rt_queued.

Fix the comment in pick_next_task_rt() to avoid confusing.
