Mel Gorman 7f60c214fd mm: migration: share the anon_vma ref counts between KSM and page migration ...

For clarity of review, KSM and page migration have separate refcounts on
the anon_vma.  While clear, this is a waste of memory.  This patch gets
KSM and page migration to share their toys in a spirit of harmony.
