Qiang Huang be6764508e Set cpuset.cpus and cpuset.mems before join the cgroup ...

It can avoid unnecessary task migrataion, see this scenario:
 - container init task is on cpu 1, and we assigned it to cpu 1,
   but parent cgroup's cpuset.cpus=2
 - we created the cgroup dir and inherited cpuset.cpus from parent as 2
 - write container init task's pid to cgroup.procs
 - [it's possibile the container init task migrated to cpu 2 here]
 - set cpuset.cpus as assigned to cpu 1
 - [the container init task has to be migrated back to cpu 1]

So we should set cpuset.cpus and cpuset.mems before writing pids
to cgroup.procs to aviod such problem.
