Subject[PATCH] sched/deadline: don't need to check throttled status when switched to dl
Date
After commit 40767b0dc768 ("sched/deadline: Fix deadline parameter 
modification handling"), deadline task throttled status is cleared
each time switch from dl, so throttled status always unset when
switch back, there is no need to check throttled status, this patch
drop the check.
