check-code: stop forbidding return code result

There is no explication of what is the intend of that check and what is the
alternative.

I suspect this comes from the transition to the "unified test" format circa
2010. With the non zero return explicitly listed in the output explicit $?
checking became Redundant. However there is valid use case for checking $? so I
am dropping this check.
