nvme: read the subsystem NQN from Identify Controller
NVMe 1.2.1 or later requires controllers to provide a subsystem NQN in the Identify controller data structures. Use this NQN for the subsysnqn sysfs attribute by storing it in the nvme_ctrl structure after verifying it. For older controllers we generate a "fake" NQN per non-normative text in the NVMe 1.3 spec.
