[PATCH -mmotm] memcg: implement memory thresholds document fixes

[Daisuke Nishimura <nishimura@mxp.nes.nec.co.jp>]

Each memcg-implement-memory-thresholds.patch and
memcg-add-interface-to-move-charge-at-task-migration.patch try to add a new
section to Documentation/cgroup/memory.txt, so the document has been a bit
mangled when these patches are merged at the same time.

This patch fixes it.
