cpusets: fix obsolete comment 

mm migration is no longer done in cpuset_update_task_memory_state() so it
can no longer take current->mm->mmap_sem, so fix the obsolete comment.

[ This changed in commit 04c19fa6f1
  ("cpuset: migrate all tasks in cpuset at once") when the mm migration
  was moved from cpuset_update_task_memory_state() to update_nodemask() ]
