powerpc/numa: Fix OF node refcounting bug
The form affinity for NUMA is set to 1 if the firmware supports OPAL. Otherwise, we have to retrieve that from OF node "/chosen". For the latter case, OF node "/chosen" reference count was never decreased. Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
