fixup! DASDDiscoverTask: use consolidated device configuration with z…

…dev (#1802482,#1937049)

As blockdev was already mocked it's not clear to me how the test would mock
that sanitize_dev_input would actually canonicalize a DASD device bus-ID.

So just check that the new code calls execWithRedirect() exactly once and
ignore the arguments.

It would be a separate fix patch to improve a fake sanitize unit test. I
suppose it would need to start with a DASD device bus-ID that is not yet
canonical/sanitized, e.g. something along the lines of:

DASDDiscoverTask("A100").run()
blockdev.s390.sanitize_dev_input.return_value = "0.0.A100"
blockdev.s390.sanitize_dev_input.assert_called_once_with("A100")
sanitized_input = blockdev.s390.sanitize_dev_input.return_value
execWithRedirect.assert_called_once_with(...)

Not sure how much value that would have, though.
