slub: Reduce #ifdef ZONE_DMA by moving kmalloc_caches_dma near dma logic
Move the definition of kmalloc_caches_dma() into a later #ifdef CONFIG_ZONE_DMA. This saves one #ifdef and leaves us with a total of two #ifdefs for dma slab support. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
