    ChunkedBackupDriver: Freeing memory on restore

    When restoring many backups, the backup service uses a lot of memory and
    when we do many concurrent restores the backup service ends up getting
    killed becase the system runs out of memory.

    This patch reduces the ref count to the data as soon as possible to let
    Python garbage collect it instead of hogging it for the whole chunk
    restore.
