KVM: nVMX: Leave VMX mode on clearing of feature control MSR When userspace sets MSR_IA32_FEATURE_CONTROL to 0, make sure we leave root and non-root mode, fully disabling VMX. The register state of the VCPU is undefined after this step, so userspace has to set it to a proper state afterward. This enables to reboot a VM while it is running some hypervisor code.
