[PATCH v4 3/5] KVM: LAPIC: Ignore timer migration when lapic timer is injected by pi

[Wanpeng Li]

From: Wanpeng Li <wanpen...@tencent.com>

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.
