devm_ioremap_resource already prints a message. For this reason, elsewhere in the kernel the check for !res before calling devm_ioremap_resource is being removed, leaving the error handling to devm_ioremap_resource. I would suggest to do the same here.
I see what you're saying, but I leave the error handling to devm_ioremap_resource(), then no one will know whether it's because the control address or the refresh address is missing. The user will just see "invalid resource" and won't what resource is actually invalid.
