[V4 PATCH 03/26] slub, hotplug: ignore unrelated node's hot-adding and hot-removing

[Lai Jiangshan <laijs@cn.fujitsu.com>]

SLUB only fucus on the nodes which has normal memory, so ignore the other
node's hot-adding and hot-removing.

so we only do something when marg->status_change_nid_normal > 0.
