After commit 40767b0dc768 ("sched/deadline: Fix deadline parameter
modification handling") is merged, deadline task throttled status
is cleared each time once switch from dl class, so throttled status
always doesn't set when switch back, there is no need to check
throttled status, this patch drop the check.
