In 8375362 we skipped the suspend check in `MountUnmountDisabler::start_transition` for transition disablers to avoid deadlocks, but that means we also need to update the assert in `~UnmountBeginMark()`. I was able to reproduce the crash locally using ThreadStateTest2.java and confirmed it is now fixed.
