In earlier versions of ZFS, ISTR that this check did not exist, and
you could do exactly this - expand a pool by adding a vdev that is not
of the same "class" as the existing vdevs on the pool.
If the vdev still existed, this could be fixed by a dumping the data
somewhere, re-creating the pool with the correct vdevs, and restoring
Otherwise, I think the only solution is to restore from backup.
Perhaps you could roll back the txg before the vdev was added, that is
way above my level of knowledge.
