nvme: add support for enhanced metadata
NVM Express ratified TP 4068 defines new protection information formats. Implement support for the CRC64 guard tags. Since the block layer doesn't support variable length reference tags, driver support for the Storage Tag space is not supported at this time. Cc: Hannes Reinecke <hare@suse.de> Cc: "Martin K.
