glusterd/quota: Heal pgfid xattr on existing data when the quota is enable
This is a backport of http://review.gluster.org/#/c/8878/ 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.
