event_notifier: prevent accidental use after close
Let's set the handles to the underlying facilities to their extremal value so no accidental misuse can happen, and to make it obvious that the notifier is dysfunctional. E.g. if we just close an fd but do not touch the int holding the fd eventually a read/write could succeed again when the fd gets reused, and corrupt the file addressed by the fd.
