KVM: SEV: Return INVALID_EVENT for SNP-only #VMGEXIT from non-SNP guest
Signal INVALID_EVENT, not MISSING_INPUT, if a non-SNP guest attempts to
invoke an SNP-only #VMGEXIT. Opportunistically move the checks out of
sev_es_validate_vmgexit() to continue the march towards making said helper
a predicate whose sole purpose is to verify the guest has marked required
GHCB fields as valid.
