exit: kill unnecessary thread_group_leader() checks in exit_notify() and do_notify_parent()

Browse source

thread_group_empty(tsk) is only possible if tsk is a group leader, and
thread_group_empty() already does the thread_group_leader() check.

So it makes no sense to check "thread_group_leader() &&
thread_group_empty()"; thread_group_empty() alone is enough.
