Even though SGLs are not supported, I gave you the patch a spin and saw the same stack traces.
Right, that patch applies only if SGL is not supported, but it's only fixing part of the problem, so I expected it would still fail.
The dma teardown needs to be symetric to the dma mapping, but we've removed the sg-table now, so we don't have the original mapping context in the completion path here. Christoph replied with a patch that tries to infer it based on the dma_addr continuity, which I think should work for you, but I'll have to look a bit closer to be confident it's always the correct assumption.
