If we already entered/are about to enter SMM, don't allow switching to INIT/SIPI_RECEIVED, otherwise the next call to kvm_apic_accept_events() will report a warning. Same applies if we are already in MP state INIT_RECEIVED and SMM is requested to be turned on. Refuse to set the VCPU events in this case.
