    sna/gen3: reset blend state after applying CA pass
    
    Otherwise we use the stale value when rendering CA glyphs directly to
    the front-buffer and subsequent rendering have a tendency to become
    invisible. (Rendering via a temporary glyph mask has a fortunate
    side-effect of reseting sufficient state to force the re-emission of the
    blend state.)
