I think that your best bet is finding the directory that triggers the panic and
then moving your data excluding that directory to a new pool.  You can try to
find the directory name in a debugger (e.g. pokinmg around frame 36) or
empirically.
Unfortunately, you have an on-disk data corruption and there is no easy way to
fix it (a hard way would be to learn ZFS on-disk format, to find the bad bits
and to somehow fix or clear them using a disk/hex editor).

There is no obvious software bug, as far as I can tell, so this report is not
actionable.
