avcodec/{h263,ituh263,msmpeg4,snow}dec: Use proper logcontext

The logging functions here can be reached by codecs without
private class, so that the log callback will receive a non-NULL
object whose AVClass pointer is NULL. Although the default log
callback handles this gracefully, it is probably an API violation.
