From: Chao Leng <lengchao@xxxxxxxxxx> All controller namespaces share the same tagset, so we can use this interface which does the optimal operation for parallel quiesce based on the tagset type(e.g. blocking tagsets and non-blocking tagsets). nvme connect_q should not be quiesced when quiesce tagset, so set the QUEUE_FLAG_SKIP_TAGSET_QUIESCE to skip it when init connect_q. Currently we use NVME_NS_STOPPED to ensure pairing quiescing and unquiescing. If use blk_mq_[un]quiesce_tagset, NVME_NS_STOPPED will be invalided, so introduce NVME_CTRL_STOPPED to replace NVME_NS_STOPPED. In addition, we never really quiesce a single namespace. It is a better choice to move the flag from ns to ctrl.
