    st/mesa: set ctx->Const.MaxSamples = 0, not 1

    The gallium docs for pipe_screen::is_format_supported() says that
    samples==0 or samples==1 both mean that multisampling is not supported.
    Return GL_MAX_SAMPLES==0 instead of 1 for consistency with other drivers.

    Note: This is a candidate for the 9.0 branch.
