cluster/dht: heal root permission post add-brick
Post add-brick event the new brick will have permission of 755
by default. If the root directory permission was other than 755,
that does not get healed to the new brick leading to permission
For choosing source of attr heal we can trust the subvols which
have layouts with latest ctime(as part of missing directory heal,
we heal the proper attr). In case none of the subvols have layout,
return ESTALE to retrigger a fresh lookup.
Note: This patch heals the permission of the root directories only.
Since, permission healing of directory is not straight forward and
required intrusive fix, those are not addressed here.
