    mesa/swrast: fix inverted front buffer rendering with old-school swrast

    I've no idea when this broke, but we have some people who wanted it fixed,
    so here's my attempt.

    reproducer, run readpix with swrast hit f, or run trival tri -sb things are
    upside down, after this patch they aren't.
