When matching remote SEP to local SEP we do not match vendor codecs properly, i.e. neither vendor ID not codec ID are checked, which may cause wrong endpoint to be selected in case there are more that one endpoints using vendor codec on remote. This patch fixes this by assinging vendor codec indentification to local SEP after it's registered and uses this information when matching SEPs.
