    BIO - Do not try to redirty a bp on error unless it has a vnode association.
    
    * vinum buffers may not have a b_vp association.  bdirty() and friends
      requires b_vp to be present.  Simply do not try to re-dirty buffers
      after a failed write unless they have a b_vp association.
    
      Note that only vinum constructs these manually-kmalloc()'d buffers
      and has this behavior.
