KVM: VMX: Register a new IPI for posted interrupt
Posted Interrupt feature requires a special IPI to deliver posted interrupt to guest. And it should has a high priority so the interrupt will not be blocked by others. Normally, the posted interrupt will be consumed by vcpu if target vcpu is running and transparent to OS. But in some cases, the interrupt will arrive when target vcpu is scheduled out. And host will see it. So we need to register a dump handler to handle it.
