[PATCH] nommu: use compound page in slab allocator

The earlier patch to consolidate mmu and nommu page allocation and
refcounting by using compound pages for nommu allocations had a bug:
kmalloc slabs who's pages were initially allocated by a non-__GFP_COMP
allocator could be passed into mm/nommu.c kmalloc allocations which really
wanted __GFP_COMP underlying pages.  Fix that by having nommu pass
__GFP_COMP to all higher order slab allocations.
