mm: vmscan: reclaim highmem zone if buffer_heads is over limit
commit 7bf52fb891b64b8d61caf0b82060adb9db761aec upstream.
We have been reclaimed highmem zone if buffer_heads is over limit but
commit 6b4f7799c6a5 ("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.
Fixes: 6b4f7799c6a5 ("mm: vmscan: invoke slab shrinkers from shrink_zone()")
