Thanks, I pushed the series. Some good catches here. Also thanks to
bug reporter.

I replaced "card" with "command" in the commit message.

I added resetting of .expecting_acmd in a separate patch.

I thought it might be possible to test what bits real cards reset in
those cases, but then it would be problematic getting the card to set
each error bit.
