genirq/cpuhotplug: Dont claim success on error
In case the affinity of an interrupt was broken, a printk is emitted. But if the affinity cannot be set at all due to a missing irq_set_affinity() callback or due to a failing callback, the message is still printed preceeded by a warning/error. That makes no sense whatsoever.
