[POWERPC] Fix smp_call_function to be preempt-safe
smp_call_function_map() was not safe against preemption to another
cpu: its test for removing self from map was outside the spinlock.
Rearrange it a little to fix that.
smp_call_function_single() was also wrong: now get_cpu() before
excluding self, as other architectures do.
