Subject: [PATCH] powerpc/numa: Avoid stupid uninitialized warning from gcc

From: Benjamin Herrenschmidt <[email-masked]>

Newer gcc are being a bit blind here (it's pretty obvious we don't
reach the code path using the array if we haven't initialized the
pointer) but none of that is performance critical so let's just
silence it.
