Actually this is a regression from the changes to st_finalize_texture
in cae2bb76.

The attached patch fixes the issue for me, and the piglit test still passes.
I don't know if it's correct in all cases though.

If the patch looks good to you I'd like to see it in the 7.10 release.

Regards,
Fredrik
