The changes introduce a memory leak for gconv steps arrays whose first element is an internal conversion, which has a fixed reference count which is not decremented. As a result, after the change in commit50ce3eae5b, the steps array is never freed, resulting in an unbounded memory leak. This reverts commit50ce3eae5b("gconv: Check reference count in __gconv_release_cache [BZ #24677]") and commit7e740ab2e7("libio: Fix gconv-related memory leak [BZ #24583]"). It reintroduces bug 24583. (Bug 24677 was just a regression caused by the second commit.)
