make do_notify_parent() __must_check, update the callers
Change other callers of do_notify_parent() to check the value it
returns, this makes the subsequent task_detached() unnecessary.
Mark do_notify_parent() as __must_check.
Use thread_group_leader() instead of !task_detached() to check
if we need to notify the real parent in wait_task_zombie().
Remove the stale comment in release_task(). "just for sanity" is
no longer true, we have to set EXIT_DEAD to avoid the races with
do_wait().
