[PATCH v12 04/46] x86/hyperv: KVM: Rename "hv_enlightenments" to "hv_vmcb_enlightenments"

[Vitaly Kuznetsov]

From: Sean Christopherson <seanjc@xxxxxxxxxx>

Now that KVM isn't littered with "struct hv_enlightenments" casts, rename
the struct to "hv_vmcb_enlightenments" to highlight the fact that the
struct is specifically for SVM's VMCB.

No functional change intended.
