KVM: SVM: Pass through GHCB MSR if and only if VM is an SEV-ES guest
Disable interception of the GHCB MSR if and only if the VM is an SEV-ES
guest. While the exact behavior is completely undocumented in the APM,
common sense and testing on SEV-ES capable CPUs says that accesses to the
GHCB from non-SEV-ES guests will #GP. I.e. from the guest's perspective,
no functional change intended.
