Add comment about leaked FileDescriptorWatcher::Controller::Watcher.
If the MessageLoopForIO is deleted before Watcher::StartWatching() runs,
|watcher_| is leaked. If the MessageLoopForIO is deleted after
Watcher::StartWatching() runs but before the DeleteSoon task runs,
|watcher_| is deleted from Watcher::WillDestroyCurrentMessageLoop().
