On real hardware, NMI button events are injected via the LINT1 line of the APICs. E.g. kdump expect this wiring and gets upset if the per-APIC LINT1 mask is not respected, i.e. if NMIs are injected to VCPUs that should not receive them. Change the APIC emulation code to reflect this. Based on qemu-kvm patch by Lai Jiangshan.
