instead of using the mdev uuid. The nvidia driver does not actually care
that it's the same as the mdev, and in qemu the uuid parameter
overwrites the smbios1 uuid internally, so we should have been reusing
that in the first place.

when i was writing the uuid appending in the first place, i was sure
that the nvidia driver needed the mdev uuid, but i was wrong
also i wrongly assumed the '-uuid' parameter does not do anything to the
guest, but it overwrites the smbios uuid. seems i misread the qemu source
code then.. (the man/help pages are not very helpful in that regard)
