fix #4553: nvidia vgpu: reuse smbios uuid for '-uuid' parameter

Browse Source 
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.
