cgroup: make cgroup hold onto its kernfs_node
cgroup currently releases its kernfs_node when it gets removed. While
not buggy, this makes cgroup->kn access rules complicated than
necessary and leads to things like get/put protection around
kernfs_remove() in cgroup_destroy_locked(). In addition, we want to
use kernfs_name/path() and friends but also want to be able to
determine a cgroup's name between removal and release.
This patch makes cgroup hold onto its kernfs_node until freed so that
cgroup->kn is always accessible.
