Source kernel commit: 40cb8613d6122ca80a9e42e4cecc4d308c3b80fb
v2/v3 inodes use di_nlink and not di_onlink; and v1 inodes use di_onlink
and not di_nlink. Whichever field is not in use, make sure its contents
are zero, and teach xfs_scrub to fix that if it is.
This clears a bunch of missing scrub failure errors in xfs/385 for
core.onlink.
