    glusterd/quota: Heal pgfid xattr on existing data when the quota is
    enable

    The pgfid extended attributes are used to construct the ancestry path
    (from the file to the volume root) for nameless lookups on files.
    As NFS relies on nameless lookups heavily, quota enforcement through NFS
    would be inconsistent if quota were to be enabled on a volume with
    existing data.

    Solution is to heal the pgfid extended attributes as a part of lookup
    perfomed by quota-crawl process. In a posix lookup check for pgfid xattr
    and if it is missing set the xattr.
