[PATCH v3] mds: Adjust mydir auth when starting MDS that was stopped cleanly

["Yan, Zheng" <zheng.z.yan@intel.com>]

From: "Yan, Zheng" <zheng.z.yan@intel.com>

When starting a MDS that was stopped cleanly, we need manually
adjust mydir's auth. This is because MDS log is empty in this case,
mydir's auth can not be adjusted during log replay.
