[PATCH 15/15] KVM: PPC: Make build work without CONFIG_VSX/ALTIVEC

[Alexander Graf <agraf-l3A5Bk7waGM@public.gmane.org>]

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.
