dht: Ignore directory with missing xattrs, which have err == 0, and start == stop
From the history (Patch: http://review.gluster.org/4668/) When subvols-per-directory is < available subvols, then there are layouts which are not populated. This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.
