Modifying preDeactivate hook in OFControllerImpl to remove double deactivation causing NPE.
The preDeactivate is needed to clean up connections when the app is deactivated but needs
to be called also when the component goes down.
If the two,app and component, go down together we should not trigger the cleaning twice.
