mm/sl[au]b: correct allocation type check in kmalloc_slab()
commit "slab: Common Kmalloc cache determination" made mistake in kmalloc_slab(). SLAB_CACHE_DMA is for kmem_cache creation, not for allocation. For allocation, we should use GFP_XXX to identify type of allocation. So, change SLAB_CACHE_DMA to GFP_DMA.
