Indeed.

It can also be more easily seen to happen with test_misalign_mmu() in
src/soc/experiment/test/test_ldst_pi.py

I guess it has to do with LoadStore1 being derived from PortInterfaceBase,
which seems to unconditionally raise addr_ok_o on receiving an addr.ok. Maybe
it should somehow consult its derived class before doing so.
