Currently, virNetDevSetCoalesce() stub is always returning error. As
it's used by virNetDevTapCreateInBridgePort(), it essentially breaks
bridged networking if coalesce is not supported.
To make it work, relax the stub to trigger error only when its
coalesce argument is not NULL, otherwise report success.
