[PATCH v9 06/14] powerpc/irq: Fix arch_local_irq_disable() in book3s

[Madhavan Srinivasan <maddy@linux.vnet.ibm.com>]

In powerpc book3s, arch_local_irq_disable() function is not a "void"
when compared to other arch. And only user for this function is
arch_local_irq_save().

Patch modify the arch_local_irq_save() and makes arch_local_irq_disable()
to use arch_local_irq_save() instead.
