cgroup: reject cgroup names with '
'

commit 71b1fb5c4473a5b1e601d41b109bdfe001ec82e0 upstream.

/proc/<pid>/cgroup contains one cgroup path on each line. If cgroup names are
allowed to contain "\n", applications cannot parse /proc/<pid>/cgroup safely.

[bwh: Backported to 3.2:
 - Adjust context
 - We have to get the name from the dentry pointer]
