Description of problem:

state_test/smm_test selftests are failing on HYGON with:
"KVM_GET_MSRS failed, r: 86 (failed on MSR c0010130)"

In order to support live migration for Hygon CSV2 guest, the commit 54378dcde7a5 ("anolis: KVM: SVM: Export MSR_AMD64_SEV_ES_GHCB to userspace for CSV2 guest") support to emulate KVM_AMD64_SEV_ES_GHCB. But it doesn't handling the return code well if the virtual machine is not a CSV2 guest.
