reporting - in my previous change, I missed the case where a mbuf
from the packet zone was freed back to the mbuf/packet keg, where
it was subsequently put into the mbuf zone and found not to contain
the expected trash.  This change adds the necessary trash_dtor call inside
mb_fini_pack so that everything is correct.

Thanks for Bosko for finding the bug and showing me how secondary zones
