cpuset: two minor code-cleanups
In cpuset_update_task_memory_state() local variable struct task_struct
*tsk = current;
And local variable tsk is used 14 times and statement task_cs(tsk) is used
twice in this function. So using task_cs(tsk) instead of task_cs(current)
is better for readability.
And "(struct cgroup_scanner *)&scan" is not good for readability also.
(and "container_of" is used in cpuset_do_move_task(), not
"(cpuset_hotplug_scanner *)scan")
