mbuf panic from a kernel with a supdate=2004.06.04.02.00.00

1. To the submitter of the problem: please sync to latest -current, the one
   you are using looks old and it might have a memory leak.

2. To Brian: Yeah, feel free to write that code.  I had it done for ctor/
   dtor, and doing it for init/fini is slightly more involved as it
   means propagating the failure upwards but leaving the object in the
   slab (or putting it back there).
