When we get the sched_slice of a sched_entity, we use cfs_rq->nr_running
to calculate the whole __sched_period. But cfs_rq->nr_running is the
number of sched_entity in that cfs_rq, rq->nr_running is the number
of all the tasks that are not throttled. So we should use the
rq->nr_running to calculate the whole __sched_period value.
