While the default "info lapic" always synchronizes cpu state ...
mon_get_cpu()
-> mon_get_cpu_sync(mon, true)
-> cpu_synchronize_state(cpu)
-> ioctl KVM_GET_LAPIC (taking KVM as example)
... the cpu state is not synchronized when the apic-id is available as
argument.
The cpu state should be synchronized when apic-id is available. Otherwise
the "info lapic <apic-id>" always returns stale data.
