Basically, you need consistent kernel and modules.  So if you have moved
to current permanently, yes, delete the 8.1 modules.

Also, to run current zfs, it seems overwhelmingly likely that you want
to run the zfs userland binaries from current, not from 8.1.

You may want to look at the various schemes for in-place updating, such
as INSTALL-NetBSD from pkgsrc/sysutils/etcmanage (my take on how to do
it), and sysupgrade (somebody else's take).

I unpack all the sets except etc/xetc, unpack etc/xetc into
/usr/netbsd-etc, and then merge the etc changes.

That really looks like you are loading 8.1 modules.  rm them, and maybe
you will get a different error.
