Commite3296cc796made the ssh block driver's error message for fingerprint mismatches more verbose, so it now prints the actual host key fingerprint and the key type. iotest 207 tests such errors, but was not amended to filter that fingerprint (which is host-specific), so do it now. Filter the key type, too, because I guess this too can differ depending on the host configuration.
