[PATCH 09/10 v2] sched/fair: Fix sched_can_stop_tick() for fair tasks

[Vincent Guittot]

We can't stop the tick of a rq if there are at least 2 tasks enqueued in
the whole hierarchy and not only at the root cfs rq.

rq->cfs.nr_queued tracks the number of sched_entity at one level
whereas rq->cfs.h_nr_enqueued tracks all enqueued tasks in the
hierarchy.
