Maxim Levitsky e34e47eb28 event_notifier: handle initialization failure better
Add 'initialized' field and use it to avoid touching event notifiers which are
either not initialized or if their initialization failed.

This is somewhat a hack, but it seems the less intrusive way to make
virtio code deal with event notifiers that failed initialization.
