  Log:
  Fix a race with the clearing of p->p_session->s_ttyvp.  NULL the pointer
  out before calling vrele() rather then after.
  
  Fix a bug with v_opencount accounting on revoke().  The underlying device
  was being closed properly but v_opencount was being decremented which causes
  it to go negative when close() is called on the descriptor later on.  To
  fix the bug we zero out v_opencount() when the underlying vnode's device
  is disassociated and spec_close() now only decrements it when the device is
  associated.
