mm: slab: make slab iterator functions static
There is no external users of slab_start/next/stop(), so make them
static. And the memory.kmem.slabinfo is deprecated, which outputs
nothing now, so move memcg_slab_show() into mm/memcontrol.c and rename
it to mem_cgroup_slab_show to be consistent with other function names.
