[PATCH 1/2] sched/fair: Fix cfs_rq_clock_pelt() for throttled cfs_rq

[Chengming Zhou]

Since commit 23127296889f ("sched/fair: Update scale invariance of PELT")
change to use rq_clock_pelt() instead of rq_clock_task(), we should also
use rq_clock_pelt() for throttled_clock_task_time and throttled_clock_task
accounting.
