  Log:
   - Try to catch the wrong bufobj panics a little earlier.  I believe they
     are actually caused by a buf with both VNCLEAN and VNDIRTY set.  In
     the traces it is clear that the buf is removed from the dirty queue while
     it is actually on the clean queue which leaves the tail pointer set.
     Assert that both flags are not set in buf_vlist_add and buf_vlist_remove.
