Subject: [PART3 Patch 05/14] oom: use N_MEMORY instead N_HIGH_MEMORY

From: Lai Jiangshan <laijs@...fujitsu.com>

N_HIGH_MEMORY stands for the nodes that has normal or high memory.
N_MEMORY stands for the nodes that has any memory.

The code here need to handle with the nodes which have memory, we should
use N_MEMORY instead.
