When doing [JDK-8351187](https://bugs.openjdk.org/browse/JDK-8351187), I apparently forgot to cover a path from `ObjectSynchronizer::quick_notify`, probably due to concurrent renames. I think we can cover this gap while still simplifying the code: let `ObjectMonitor` handle all events, DTrace, JFR, OM stats.
