slub: Remove node check in slab_free

We can set the page pointing in the percpu structure to
NULL to have the same effect as setting c->node to NUMA_NO_NODE.

Gets rid of one check in slab_free() that was only used for
forcing the slab_free to the slowpath for debugging.

We still need to set c->node to NUMA_NO_NODE to force the
slab_alloc() fastpath to the slowpath in case of debugging.
