mm: memory.numa_stat: fix file permission

Browse Source 
Commit 406eb0c9ba76 ("memcg: add memory.numastat api for numa
statistics") adds memory.numa_stat file for memory cgroup.  But the file
permissions are wrong.

  [kamezawa@bluextal linux-2.6]$ ls -l /cgroup/memory/A/memory.numa_stat
  ---------- 1 root root 0 Jun  9 18:36 /cgroup/memory/A/memory.numa_stat

This patch fixes the permission as

  [root@bluextal kamezawa]# ls -l /cgroup/memory/A/memory.numa_stat
  -r--r--r-- 1 root root 0 Jun 10 16:49 /cgroup/memory/A/memory.numa_stat
