Modify interrupt load balancing policy on reboot/stop

Browse Source 
When rebooting:
1. Stop irqbalance
2. Modify /proc/irq/*/smp_affinity so that McKernel cores are not
   included
3. Start irqbalance with McKernel cores and IHK IRQ banned from
   load balancing

When stopping:
1. Stop irqbalance
2. Restore /proc/irq/*/smp_affinity
3. Restart irqbalance with the system default settings
