cpuset: initialize cpuset a bit early
Now we call ss->bind() in cgroup_init(), so cgroup_init() will
call cpuset_bind() and then the latter will access top_cpuset's
cpumask, which is NULL, because cpuset_init() is called after
cgroup_init()
The simplest fix is to swap cgroup_init() and cpuset_init().
