Sebastian Andrzej Siewior 386ef214c3 sched: Teach the forced-newidle balancer about CPU affinity limitation. 
try_steal_cookie() looks at task_struct::cpus_mask to decide if the
task could be moved to `this' CPU. It ignores that the task might be in
a migration disabled section while not on the CPU. In this case the task
must not be moved otherwise per-CPU assumption are broken.

Use is_cpu_allowed(), as suggested by Peter Zijlstra, to decide if the a
task can be moved.

Fixes: d2dfa17bc7 ("sched: Trivial forced-newidle balancer")
