Niels de Vos 49c6784c5c ci: deploy/jjb.sh should fail on wrong arguments
In case the '--cmd' option is missing, usage() will be called and the
script exits with 0. A missing option is a failure, so make usage()
return and handle the exit status when usage() got called instead.

# Create a new Job in OCP that runs the jbb-validate container once. This
# script will wait for completion of the validation, and uses the result of the
# container to report the status.
#
# Usage:
# - arguments to the script can be "validate" or "deploy"
# - the GIT_REF environment variable is injected in the batch job so that it
# can use a particular GitHub PR
#
# error out in case a command fails
