genirq: Make the cpuhotplug migration code less noisy
genirq: Make the cpuhotplug migration code less noisy

The original arm code has a pr_debug() statement for the case where
the irq chip has no set_affinity() callback. That's sufficient for
debugging and we really don't want to spam dmesg with useless warnings
for the normal case.
