Skip printing a retune error when we scan for a removed card because we
then expect a failed command.

In my tests, detect_change was only set when a card was removed.
Inserting a card or resuming from RPM would print an error. Did I
overlook somethign or is this good to go?

So, what about this to remove the bogus 'retune failure' command?
I also think the code is a tad more readable this way.

Seems OK to me, but needs re-base. Nevertheless:

I did the rebase myself and applied it for next, thanks to both of you!
