Bashate warned on init-swift.sh because of E043 -- arithmetic compound has inconsistent return semantics: (( next_port++ )) New Zuul reported that on every change as a warning. This is fixed here. This change makes Bashate always produce errors so that we do not introduce such warnings again. Change-Id: I40166b377ec2580e17901375b636183bca492d3a
