  SVN rev 193172 on 2009-05-31 14:52:45Z by kib
  
  Lock the real null vnode lock before substitution of vp->v_vnlock.
  This should not really matter for correctness, since vp->v_lock is
  not locked before the call, and null_lock() holds the interlock,
  but makes the control flow for reclaim more clear.
