xfs: repair link count of nondirectories after rebuilding parent pointers

Browse source

Since the parent pointer scrubber does not exhaustively search the
filesystem for missing parent pointers, it doesn't have a good way to
determine that there are pointers missing from an otherwise uncorrupt
xattr structure.  Instead, for nondirectories it employs a heuristic of
comparing the file link count to the number of parent pointers found.

However, we don't want this heuristic flagging a false corruption after
a repair has actually scanned the entire filesystem to rebuild the
parent pointers.  Therefore, reset the file link count in this one case
because we actually know the correct link count.
