From: Glauber Costa <glom...@parallels.com>
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.
