Steve Muckle 00292ad78e sched: remove migration notification from RT class ...

Commit 88a7e37d26 (sched: provide per cpu-cgroup option to
notify on migrations) added a notifier call when a task is moved
to a different CPU. Unfortunately the two call sites in the RT
sched class where this occurs happens with a runqueue lock held.
This can result in a deadlock if the notifier call attempts to do
something like wake up a task.

Fortunately the benefit of 88a7e37d26 comes mainly from notifying
on migration of non-RT tasks, so we can simply ignore the movements
of RT tasks.
