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.
