sched: Add wrapper for checking task_struct::on_rq
Implement task_on_rq_queued() and use it everywhere instead of on_rq check. No functional changes. The only exception is we do not use the wrapper in check_for_tasks(), because it requires to export task_on_rq_queued() in global header files. Next patch in series would return it back, so we do not twist it from here to there.
