s390x/flic: introduce inject_airq callback
Let's introduce a specialized way to inject adapter interrupts that, unlike the common interrupt injection method, allows to take the characteristics of the adapter into account. For adapters subject to AIS facility: - for non-kvm case, we handle the suppression for a given ISC in QEMU. - for kvm case, we pass adapter id to kvm to do airq injection. Add add tracepoint for suppressed airq and suppressing airq.
