[XFS] keep i_nlink updated and use proper accessors
To get the read-only bind mounts in -mm to work correctly with XFS we need to call the drop_nlink and inc_nlink helpers to monitor the link count. Add calls to these to xfs_bumplink and xfs_droplink and stop copying over di_nlink to i_nlink in xfs_validate_fields and vn_revalidate.
