As a follow on to the recent rework of __cxl_parse_cfmws() to always return errors [1], use cleanup.h helpers to remove goto and other cleanups now that logging is moved to the cxl_parse_cfmws() wrapper. This ends up adding more code than it deletes, but __cxl_parse_cfmws() itself does get smaller. The takeaway from the cond_no_free_ptr() discussion [2] was to not add new macros to handle the cases where no_free_ptr() is awkward, instead rework the code to have helpers and clearer delineation of responsibility. Now one might say that __free(del_cxl_resource) is excessive given it is immediately registered with add_or_reset_cxl_resource(). The rationale for keeping it is that it forces use of "no_free_ptr()" on the argument passed to add_or_reset_cxl_resource(). That in turn makes it clear that @res is NULL for the rest of the function which is part of the point of the cleanup helpers, to turn subtle use after free errors [3] into loud NULL pointer de-references.
