powerpc/mm: Eliminate unneeded for_each_memblock
The only persistent change made by this loop is calling memblock_set_node() once for each memblock, which is not useful (and has no effect) as memblock_set_node() is not called with any memblock-specific parameters. Subsistute a single memblock_set_node(). Signed-off-by: Cody P Schafer <cody@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
