Paul E. McKenney 4d084617fb sparc64: Prevent sparc64 from invoking irq handlers on offline CPUs ...

Make sparc64 refrain from clearing a given to-be-offlined CPU's bit in the
cpu_online_mask until it has processed pending irqs.  This change
prevents other CPUs from being blindsided by an apparently offline CPU
nevertheless changing globally visible state.
