x86/reboot: Assert that IRQs are disabled when turning off virtualization
Assert that IRQs are disabled when turning off virtualization in an
emergency. KVM enables hardware via on_each_cpu(), i.e. could re-enable
hardware if a pending IPI were delivered after disabling virtualization.
Remove a misleading comment from emergency_reboot_disable_virtualization()
about "just" needing to guarantee the CPU is stable (see above).
