Bug Description
When detaching multiple NVMe-oF volumes from the same host we may end with a NVMe subsystem in "connecting" state, and we'll see a bunch nvme error in dmesg.
This happens on storage systems that share the same subsystem for multiple volumes because Nova has not been updated to support the tri-state "shared_targets" option that groups the detach and unmap of volumes to prevent race conditions.
