[patch 26/55] genirq/cpuhotplug: Dont claim success on error

[Thomas Gleixner]

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.
