    mountd: do not warn about using class mask with -mask
    
    The previous code would warn that the mask was being defaulted to
    an obsolete class mask even if -mask was present after -network.
    Import a fix from Peter Much with a little tweaking, deferring the
    warning until after all parameters are processed.
