xfs: adjust parent pointer scrubber for sb-rooted metadata files

Starting with the metadata directory feature, we're allowed to call the
directory and parent pointer scrubbers for every metadata file,
including the ones that are children of the superblock.

For these children, checking the link count against the number of parent
pointers is a bit funny -- there's no such thing as a parent pointer for
a child of the superblock since there's no corresponding dirent.  For
purposes of validating nlink, we pretend that there is a parent pointer.
