Sean Christopherson 427c76aed2 KVM: x86/mmu: Bug the VM if write-tracking is used but not enabled 
Bug the VM if something attempts to write-track a gfn, but write-tracking
isn't enabled.  The VM is doomed (and KVM has an egregious bug) if KVM or
KVMGT wants to shadow guest page tables but can't because write-tracking
isn't enabled.
