slub: do not put a slab to cpu partial list when cpu_partial is 0
In free path, we don't check number of cpu_partial, so one slab can be linked in cpu partial list even if cpu_partial is 0. To prevent this, we should check number of cpu_partial in put_cpu_partial(). Acked-by:Christoph Lameeter <cl@linux.com> Reviewed-by:
