sched: add READ_ONCE to task_on_rq_queued
task_on_rq_queued read p->on_rq without READ_ONCE, though p->on_rq is
set with WRITE_ONCE in {activate|deactivate}_task and smp_store_release
in __block_task, and also read with READ_ONCE in task_on_rq_migrating.
Make all of these accesses pair together by adding READ_ONCE in the
task_on_rq_queued.
