Subject: [PATCH 0/2] x86/kvm/hyper-v: fix KVM_CAP_HYPERV_ENLIGHTENED_VMCS

Commit e2e871ab2f02 ("x86/kvm/hyper-v: Introduce nested_get_evmcs_version()
helper") broke KVM_CAP_HYPERV_ENLIGHTENED_VMCS: the returned evmcs version
is always zero now. Fix the issue and add a check to evmcs selftest.

The offending commit is in 5.0-rc1, it would be great if the fix could be
queued before 5.0.
