Track "virtual NMI exposed to L1" via a governed feature flag instead of using a dedicated bit/flag in vcpu_svm. Note, checking KVM's capabilities instead of the "vnmi" param means that the code isn't strictly equivalent, as vnmi_enabled could have been set if nested=false where as that the governed feature cannot. But that's a glorified nop as the feature/flag is consumed only by paths that are gated by nSVM being enabled.
