Yongpeng Yang 4b2b03151e zloop: use READ_ONCE() to read lo->lo_state in queue_rq path ...

In the queue_rq path, zlo->state is accessed without locking, and direct
access may read stale data. This patch uses READ_ONCE() to read
zlo->state and data_race() to silence code checkers, and changes all
assignments to use WRITE_ONCE().
