config.c: fix memory leak in convert_controller_versions()

Fix memory leak warning in convert_controller_versions(), reported by
Coverity tool:

CID 313911 (#1 of 1): Resource leak (RESOURCE_LEAK)9. leaked_storage:
Variable cgrp_cpy going out of scope leaks the storage it points to.

struct cgroup cgrp_cpy was not free'd in the success path, fix it.
