default priority. This handles the case when
pri_spec->stream_id == stream_id. This happens because we
don't check pri_spec->stream_id against new stream ID in
nghttp2_submit_request. This also handles the case when idle
stream created by PRIORITY frame was opened. Somehow we
first remove the idle stream from dependency tree. This is
done to simplify code base, but ideally we should retain old
dependency. But I'm not sure this adds values. */
