In preparation for moving vcpu allocation to common PPC code, add an explicit, albeit redundant, build-time assert to ensure the vcpu member is located at offset 0. The assert is redundant in the sense that kvmppc_core_vcpu_create_e500() contains a functionally identical assert. The motiviation for adding the extra assert is to provide visual confirmation of the correctness of moving vcpu allocation to common code.
