Pass the error to inject_listener_closed method (#1517)

Browse Source 
* Pass the error to inject_listener_closed method

If there is an error when the listener closes, found in the
`NetworkEvent::ListenerClosed` `reason` field, we would like to pass it
on to the `inject_listener_closed()` method so that implementors of this
method have access to it.

Add an error parameter to `inject_listener_closed`.  Convert the
`reason` field from a `Result` to an `Option` and if there is an error
pass `Some(error)` at the method call site.

* Pass 'reason' as a Result

* Finish change
