    bhyve nvme: Fix Identify Namespace, NSID=ffffffff
    
    If the NVMe Controller doesn't support Namespace Management, it should
    return "Invalid Namespace or Format" when the Host request Identify
    Namespace with the global NSID value.
    
    Fixes UNH IOL 16.0 Test 9.1, Case 6
    
    (cherry picked from commit ac678b4aaf1e852aa033906eabee7322d985c810)
