[PATCH 6/5] xfs_repair: don't re-add root dotdot if root dir was rebuilt

[Eric Sandeen <sandeen@xxxxxxxxxxx>]

If we've rebuilt the root directory, ".." was taken
care of, so clear need_root_dotdot.

Otherwise it will be added twice, and a subsequent repair
will say:

 entry ".." (ino 5824) in dir 5824 is a duplicate name, would junk entry

(sorry for 6/5, this just popped out and is similar to the
patch 3/5 I just sent, so probably worth doing at the same time.
