KVM: PPC: Make build work without CONFIG_VSX/ALTIVEC
The FPU/Altivec/VSX enablement also brought access to some structure
elements that are only defined when the respective config options
are enabled.
Unfortuately I forgot to check for the config options at some places,
so let's do that now.
Unbreaks the build when CONFIG_VSX is not set.
