  Log:
  SVN rev 206798 on 2010-04-18 12:50:26Z by pho
  
  Fix incorrect assertion. If the caller passed in no lock flags
  (i.e. just checking the vnode for validity) then there is a window
  between the VI_UNLOCK() in _vn_lock(9) and the subsequent VI_LOCK()
  in vget() where another thread could have set VI_DOOMED.
