cpuset: fix error handling regression in proc_cpuset_show()



4c737b41 ("cgroup: make cgroup_path() and friends behave in the
style of strlcpy()") botched the conversion of proc_cpuset_show() and
broke its error handling.  It made the function return 0 on failures
and fail to handle error returns from cgroup_path_ns().  Fix it.
