Make nvme_ns_remove match the assumptions elsewhere. 1) !NVME_NS_READY needs to be srcu synchronized to make sure nothing is running in __nvme_find_path or nvme_round_robin_path that will re-assign this ns to current_path. 2) Any matching current_path entries need to be cleared before removing from the siblings list, to prevent calling nvme_round_robin_path with an "old" ns that's off list. 3) Finally the list_del_rcu can happen, and then synchronize again before releasing any reference counts.
