sched: rework of "prioritize non-migratable tasks over migratable ones"
(1) handle in a generic way all cases when a newly woken-up task is
not migratable (not just a corner case when "rt_se->nr_cpus_allowed ==
1")
(2) if current is to be preempted, then make sure "p" will be picked
up by pick_next_task_rt().
i.e. move task's group at the head of its list as well.
currently, it's not a case for the group-scheduling case as described
