Currently NVMe controller cannot set Model Number/Firmware Version, and if Serial Number contains white space, it cannot set since parse option will fail. In some scenario, user try to clone the hosts NVMe identify for some reasons.

This patch will enable guest clone such informations as follow fields:

Vendor ID
Subsystem Vendor ID
Serial Number
Model Number
Firmware Version
IEEE OUI Identifier

Inside guest, check the nvmecontrol identify output.
