Igor Mammedov c5be7517d6 x86: cpuhp: prevent guest crash on CPU hotplug when broadcast SMI is in use 
There were reports of guest crash on CPU hotplug, when using q35 machine
type and OVMF with SMM, due to hotplugged CPU trying to process SMI at
default SMI handler location without it being relocated by firmware first.

Fix it by refusing hotplug if firmware hasn't negotiated CPU hotplug with
SMI support while SMI broadcast is in use.
