This defines a nmi_monitor_handler() callback for i386 CPU class. This removes #ifdef I386 branch in qmp_inject_nmi so new i386's nmi() callback is going to be used for NMI. This changes code to inject NMI on the current CPU instead of injecting it on every CPU. However that does not seem to be an issue. Since kvm_apic_external_nmi() takes care of preforming operations in the specific CPU thread so no extra measure is required here.
