[PATCH 1/3] utrace_do_stop: don't set ->stopped when ->exit_state

[Oleg Nesterov]

The logic is correct. Just I think it would be tidier to avoid setting
utrace->stopped when the task is dead. It doesn't hurt, but it is not
needed (and _looks_ confusing imho).

We can just return true, this is enough for the caller.

In fact, it seems to me "if (exit_state)" case is not needed at all,
see "[PATCH 3/3]".
