Use complete streams for scale and speed.
Without this patch it's always stream0 that is used to get segment event that is used to set scale and speed. This even if client not doing SETUP for stream0. At least in suspend mode reset this not working since then it's just random if send_rtp_sink have got any segment event. There are no check if send_rtp_sink for stream0 got any data before media is prerolled after PLAY request.
