vmscan: prevent shrinking of active anon lru list in case of no swap space V3
shrink_zone() can deactivate active anon pages even if we don't have a
swap device. Many embedded products don't have a swap device. So the
deactivation of anon pages is unnecessary.
This patch prevents unnecessary deactivation of anon lru pages. But, it
don't prevent aging of anon pages to swap out.
