sched/cache: Ignore non-fair current in alb_break_llc()

Commit d6b9afab44e23 ("sched/cache: Fix
checking active load balance by only considering the CFS task")
stopped using task_util() for non-fair cur.

__active_load_balance_cpu_stop() calls detach_one_task(), that only looks
to cfs_tasks list. So if the rq->curr is not fair, doing a decision
according to it is wrong, since we only migrate tasks that is fair.

Commit f0d243a96f26 ("sched/fair: Avoid creating misfits during
cache-aware balancing") passes cur to task_misfits_asym_cpu()
without checking if the cur is in fair class or not. Fix this.
