    glx: remove miss leading comment
    
    There was a comment implying that if a rgba config has been requested
    but no suitable config was found then we would automatically fall back
    to an rgb config instead. Actually if no rgba visual is found we simply
    fail without any automatic fall back because Cogl is not in a good
    position to judge if automatic fall backs are acceptable for higher
    level apis such as clutter.
