Commit 8f618968 changed stop_task to do the same bookkeping as the other classes. However, the call to cpuacct_charge() doesn't affect the scheduler decisions at all, and doesn't need to be moved over. Moreover, being a kthread, the migration thread won't belong to any cgroup anyway, rendering this call quite useless.
