msm_irqbalance balances IRQs across CPUs, which collides with SBalance.

18de03d1a6 kernel: Don't allow userspace to alter IRQ affinities 
The msm_irqbalance service in userspace constantly migrates IRQs between
CPUs according to its whims, which is not desired. All of the IRQs have
a sane affinity (CPU0 if unimportant, CPU4-7 otherwise), so prevent
userspace from tampering with that.
