mm: vmscan: reclaim highmem zone if buffer_heads is over limit

Browse source

commit 7bf52fb891 upstream.

We have been reclaimed highmem zone if buffer_heads is over limit but
commit 6b4f7799c6 ("mm: vmscan: invoke slab shrinkers from
shrink_zone()") changed the behavior so it doesn't reclaim highmem zone
although buffer_heads is over the limit.  This patch restores the logic.
