    quota: Fix incorrect disk usage shown on a tiered volume

    When quota is enabled on a tiered volume, incorrect data usage is
    shown, it is because, during the process of migrating files in tiering,
    we are accounting both for the src file and dst file at some point. By the
    time we make the srcfile as a T file, marker has already accounted the
    contri and has updated it's parent and also we are not accounting for the
    truncate operation done, which accounts to incorrect data usage even after
    unlinking the file. The size can increase drastically with multiple
promotes
    and demotes since the contri keeps changing and the parent is being
updated.
