    nvmecontrol: Display Metadata and Sanitize capabilities of the device
    
    Determine if a device supports "Extended" or "Separate" metadata, and
    what the current metadata setting is (None, Extended, Separate)
    
    Also determine if the device supports:
      - Sanitize Crypto Erase
      - Sanitize Block Erase
      - Sanitize Overwrite
