[RFC PATCH v2 6/7] sched/fair: fix h_nr_runnable accounting with per-task throttle

[Aaron Lu]

Task based throttle does not adjust cfs_rq's h_nr_runnable on throttle
anymore but relies on standard en/dequeue_entity(), so there is no need
to take special care of h_nr_runnable in delayed dequeue operations.
