    Fix the order of arguments of client copyLoop to match the call.
    
    The call was
            copyLoop(socks, snowflake)
    but the function signature was
            func copyLoop(WebRTC, SOCKS io.ReadWriter) {
    
    The mistake was mostly harmless, because both arguments were treated the
    same, except that error logs would have reported the wrong direction.
