[PATCH v3 3/4] KVM: LAPIC: Ignore timer migration when lapic timer is injected by posted-interrupt

[Wanpeng Li]

From: Wanpeng Li <wanpengli@xxxxxxxxxxx>

When lapic timer is injected by posted-interrupt, the emulated timer is
offload to the housekeeping cpu. The timer interrupt will be delivered
properly, no need to migrate timer.
