Allan Jude ae5a522cae 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
