When irqblance attempts writes to the IPI smp_affinity (ie.
/proc/irq/16/smp_affinity in the above example) it fails but irqbalance
ignores currently ignores this.
This patch catches these write fails and in this case adds that IRQ

Good point thanks... new patch below

irqbalance, powerpc: add IRQs without settable SMP affinity to banned list
On pseries powerpc, IPIs are registered with an IRQ number so
/proc/interrupts
