Subject: [PATCH] rmap: always add new vmas at the end

Make sure to always add new VMAs at the end of the list.  This is
important so rmap_walk does not miss a VMA that was created during the
rmap_walk.

The old code got this right most of the time due to luck, but was buggy
when anon_vma_prepare reused a mergeable anon_vma.
