nvme-multipath: avoid crash on invalid subsystem cntlid enumeration A process holding an open reference to a removed disk prevents it from completing deletion, so its name continues to exist. A subsequent gendisk creation may have the same cntlid which risks collision when using that for the name. Use the unique ctrl->instance instead.
