[1/2] changes sync_pir_to_irr interface to avoid a definitely superfluous KVM_REQ_EVENT in [2/2]. It's possible that we don't need KVM_REQ_EVENT, but a slight slowdown in execution is worth the time needed for a proof. (A quick test showed that KVM_REQ_EVENT is always already set if sync_pir_to_irr does something.) [2/2] is applicable to userspace split IOAPIC as well, but I hope that we want it to work like normal IOAPIC (no ACK for edge irq), so I haven't fixed it.
