Subject: Add stubs to ignore effective IRQ affinity

Patch-mainline: Never, only needed for less conflicts from upstream commits

References: FATE#323954

Upstream got a new effective affinity framework which we're missing in our

downstream tree. Add a few stubs that allow us to take upstream code

nevertheless and reuse it.
