[XFS] keep i_nlink updated and use proper accessors

Browse Source 
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.
