I fear my commit message (but not the code) might be wrong.
irq_create_affinity_masks can return NULL any time we don't have any
affinity masks. I've already had a discussion about this elsewhere
with Bjorn, and I suspect we need to kill the warning or move it
to irq_create_affinity_masks only for genuine failure cases.
