Improve error message when create_topic fails

[sloretz]

This improves the error message when creating a topic fails. The return codes are the documented return codes for dds_create_topic_generic and dds_create_topic_sertype, which is what create_topic() uses depending on the preprocessor definition DDS_HAS_DDSI_SERTYPE.

I'd like this to be backported to Humble - it can probably be backported to other distro's too.
