xfs: mark dir corrupt when lookup-by-hash fails
In xchk_dir_actor, we attempt to validate the directory hash structures by performing a directory entry lookup by (hashed) name. If the lookup returns ENOENT, that means that the hash information is corrupt. The _process_error functions don't catch this, so we have to add that explicitly. Signed-off-by: Darrick J.
