Detect wrong password during 'open' command

When a wrong password is entered when attempting to open the encrypted
volume the nitrokey will report that in the form of an error. In such a
case we should retry the operation after asking the user for the
corrected password.
This change implements this logic. Note that because we use gpg-agent
for the PIN inquiry and because it caches passwords by default we must
make sure to clear the cache before retrying.
