    dht: report constant directory size

    Directory size is meaningless.  Every filesystem has its own
    unpredictable way of increasing or decreasing it, based on internal data
    structures and even transient conditions.  Some filesystems (e.g. ext4)
    never decrease it at all.  Others (e.g. btrfs) don't even report it.
    Very few programs look at it, and those that do are broken.
    Unfortunately, one such program is GNU tar, which will complain when it
    sees different values because at different times we got the value from
    different DHT subvolumes.  To avoid such problems, just report a
    constant value.
