Subject: wait_task_stopped(): remove unneeded delay_group_leader check
From: Oleg Nesterov <oleg@xxxxxxxxxx>
wait_task_stopped() doesn't need the "delay_group_leader" parameter. If
the child is not traced it must be a group leader. With or without
subthreads ->group_stop_count == 0 when the whole task is stopped.
