From: Darrick J. Wong <djwong@xxxxxxxxxx>
Teach the online repair code to fix directory '..' entries (aka
directory parent pointers). Since this requires us to know how to scan
every dirent in every directory on the filesystem, we can reuse the
parent scanner components to validate (or find!) the correct parent
entry when rebuilding directories too.
