Thank you for the suggestion. I moved the decoder unpacking checks from
cxl_test to a KUnit suite in v16. The uncommitted decoder case no longer
checks the target type.
The test layout follows your proposed CXL KUnit infrastructure and has
some duplication. Once your series lands, I'll rebase these tests onto it.
