kernel - sysref - Fix vnode interlock for 1->0 transition

* When the vnode refcount drops to 0 vnode_terminate() is called.  This
  function previously acquired the vx_lock() after the 1->0 transition.

  Instead integrate the acquisition of the vx_lock() into the 1->0
  transition to close a small MP race.
