 - Assert that the bufobj matches in flushbuflists.  I still haven't gotten    to root cause on exactly how this happens.  - If the assert is disabled, we presently try to handle this case, but the    BUF_UNLOCK was missing.  Thus, if this condition ever hit we would leak    a buf lock.

Many thanks to Peter Holm for all his help in finding this bug.  He really
put more effort into it than I did.
