cgroup: fix error handling regressions in proc_cgroup_show() and cgroup_release_agent()

Browse source

4c737b41de ("cgroup: make cgroup_path() and friends behave in the
style of strlcpy()") broke error handling in proc_cgroup_show() and
cgroup_release_agent() by not handling negative return values from
cgroup_path_ns_locked().  Fix it.
