slub: Fix bad boundary check in init_kmem_cache_nodes()
Function init_kmem_cache_nodes is incorrect when checking upper limitation of kmalloc_caches. The breakage was introduced by commit 91efd773c74bb26b5409c85ad755d536448e229c ("dma kmalloc handling fixes"). Acked-by: Christoph Lameter <cl@linux-foundation.org> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
