It seems another case when irq_set_affinity is NULL whenever affinity is changed or not before that,
For this case, I suppose the chip is not supporting set_affinity, then the chip should set all
related irqs into just CPU0, otherwise, it will bring some trouble, do you agree?

I guess this case should be covered outside fixup_irqs() code.
