[PATCH v2 14/15] sched/deadline: Do not restart the DL server on replenish from timer

[Joel Fernandes (Google)]

There is no point in doing so if there are no CFS tasks to run. If there
were, we would be doing ENQUEUE_REPLENISH from the dl_task_timer,
instead of calling replenish_dl_entity(). Fix that.
