powerpc/module_64: fix array_size.cocci warning
Fix following coccicheck warning: ./arch/powerpc/kernel/module_64.c:432:40-41: WARNING: Use ARRAY_SIZE. ARRAY_SIZE(arr) is a macro provided by the kernel. It makes sure that arr is an array, so it's safer than sizeof(arr) / sizeof(arr[0]) and more standard.
