We wanted to re-enable it once the 7.1 tree has opened (which is now), but to do so, we should also fix the bug reported in https://gitlab.com/qemu-project/qemu/-/issues/945 . Patches 1 and 2 fix that problem (I hope), patch 3 re-enables the assertion, and patch 4 adds a regression test for issue 945.
