[PATCH] slab.c ifdef reduction breaks build

[Jeff Dike <jdike@addtoit.com>]

optional-zone_dma-in-the-vm-no-gfp_dma-check-in-the-slab-if-
no-config_zone_dma-is-set-reduce-config_zone_dma-ifdefs converts some
ifdefs into ifs.

One of them causes cs_dmacachep to be referenced, when that field
doesn't exist, because it's ifdefed on CONFIG_ZONE_DMA.

I'd suggest reverting that chunk.
