From: Daniel P. Berrangé <berrange@redhat.com>

When waiting for expected output, the 'success_message' is a mandatory
parameter, with 'failure_message' defaulting to None.

The code has logic which indicates it was trying to cope with
'success_message' being None and 'failure_message' being non-None but
it does not appear able to actually do anything useful. The check for
'success_message is None' will break out of the loop before any check
for 'failure_message' has been performed.

IOW, for practcal purposes 'success_message' must be non-None unless
'send_string' is set. Assert this expectation and simplify the loop
logic.
