Don't parse media stream state for SIP video streams

The sendonly/recvonly/sendrecv/inactive media stream attributes were
parsed for video, but nothing was ever done with them.  With this code
removed, an UNSUPPORTED message is produced when these attributes are
used in conjunction with a video stream which is the better behavior
since they were never really supported in the first place.
