panic: handle_written_inodeblock: live inodedep

With RELENG_5_2 cvsupped shortly after -RC2, today I got a panic after
reboot from a crash, while background fsck was running:

panic: handle_written_inodeblock: live inodedep

Dump is 1 GB, and I will keep it around a few days.  I'm going to update
to todays RELENG_5_2 right here and now, but will keep the old sources
which are on backup, just in case.
