event_notifier: avoid dandling file descriptor in event_notifier_cleanup

Browse Source 
If rfd is equal to wfd the file descriptor is closed but
rfd will still have the closed value.
The EventNotifier structure should not be used again after calling
event_notifier_cleanup or should be initialized again but make
sure to not have dandling file descriptors around.
