wait_task_zombie: don't fight with non-existing race with a dying ptracee
The "p->exit_signal == -1 && p->ptrace == 0" check and the comment are
bogus. We already did exactly the same check in eligible_child(), we did
not drop tasklist_lock since then, and both variables need
write_lock(tasklist) to be changed.
