when SMP VM start, AP may lost INIT because of receiving INIT between
kvm_vcpu_ioctl_x86_get/set_vcpu_events.
vcpu 0 vcpu 1
kvm_vcpu_ioctl_x86_get_vcpu_events
events->smi.latched_init=0
send INIT to vcpu1
set vcpu1's pending_events
kvm_vcpu_ioctl_x86_set_vcpu_events
events->smi.latched_init == 0
clear INIT in pending_events
considering migration, just at level >= KVM_PUT_RESET_STATE,
add KVM_VCPUEVENT_VALID_SMM in events.flags.I think it is better to
modify in qemu.
