nvme: avoid to use blk_mq_abort_requeue_list()
NVMe may add request into requeue list simply and not kick off the requeue if hw queues are stopped. Then blk_mq_abort_requeue_list() is called in both nvme_kill_queues() and nvme_ns_remove() for dealing with this issue. Unfortunately blk_mq_abort_requeue_list() is absolutely a race maker, for example, one request may be requeued during the aborting. So this patch just calls blk_mq_kick_requeue_list() in nvme_kill_queues() to handle this issue like what nvme_start_queues() does. Now all requests in requeue list when queues are stopped will be handled by blk_mq_kick_requeue_list() when queues are restarted, either in nvme_start_queues() or in nvme_kill_queues().
