core: corrects check of strduped controller string

In commit 246aa6d (core: add bus API and systemctl commands for altering
cgroup parameters during runtime), when rewriting unit_add_one_default_cgroup
to prefered style, the check of strduped b->controller was incorrectly
changed to check the containing structure. Correct it.
