[Why] previously event_property_validate was only called after we enabled the display. But after "Refactor HDCP to handle multiple displays per link" this function can be called at any time. In certain cases we don't have a aconnector [How] Null check aconnector and exit early. This is ok because we only need to check the ENABLED->DESIRED transition if a connector exists.
