Ming Lei 806f026f9b nvme: use blk_mq_start_hw_queues() in nvme_kill_queues() ... Inside nvme_kill_queues(), we have to start hw queues for draining requests in sw queues, .dispatch list and requeue list, so use blk_mq_start_hw_queues() instead of blk_mq_start_stopped_hw_queues() which only run queues if queues are stopped, but the queues may have been started already, for example nvme_start_queues() is called in reset work function. blk_mq_start_hw_queues() run hw queues in current context, instead of running asynchronously like before. Given nvme_kill_queues() is run from either remove context or reset worker context, both are fine to run hw queue directly. And the mutex of namespaces_mutex isn't a problem too becasue nvme_start_freeze() runs hw queue in this way already.
