File vga-fix-cirrus-bios.patch of Package qemu.16512

Subject: vga: fix cirrus bios

Git-commit: d11c75185276ded944f2ea0277532b7fee849bbc

Little mistake, big effect.  The patch adding the ati driver broke
cirrus due to a missing "else", which effectively downgrades cirrus
to standard vga.

Fixes: 34b6ecc16074 ("vga: add atiext driver")
