You could try doing a zfs send ... | zfs recv ... to create a new copy of the affected ZFSes. This should pretty much unwind any effect of having had deduplication turned on. Then it's a matter of using 'zfs rename' to move the new copy into the expected locations in your zfs hierarchy and have them mount at the correct places in your filesystem. That's something you'll almost certainly need to do while booted from a live CD or similar.
