Tejun Heo fa5ff8a1c4 cgroup: fix and restructure error handling in copy_cgroup_ns() 
copy_cgroup_ns()'s error handling was broken and the attempt to fix it
d22025570e ("cgroup: fix alloc_cgroup_ns() error handling in
copy_cgroup_ns()") was broken too in that it ended up trying an
ERR_PTR() value.

There's only one place where copy_cgroup_ns() needs to perform cleanup
after failure.  Simplify and fix the error handling by removing the
goto's.
