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.
