    sna/dri2: Keep the most-recent back buffer cache when reaping on idle

    When the client misses a swap, we consider it idle and unlikely to swap
    again for a while. We try to take advantage of that and remove the old
    back buffers. But it is likely to swap again and so having some of that
    cache around would be advantageous.
