  SVN rev 180682 on 2008-07-21 23:01:09Z by attilio
  
  - Disallow XFS mounting in write mode.  The write support never worked really
    and there is no need to maintain it.
  - Fix vn_get() in order to let it call vget(9) with a valid locking
    request.  vget(9) returns the vnode locked in order to prevent recycling,
    but in this case internal XFS locks alredy prevent it from happening, so
    it is safe to drop the vnode lock before to return by vn_get().
  - Add a VNASSERT() in vget(9) in order to catch malformed locking requests.
