UUID in D-Bus interface in SMBIOS MDR V2 will disappear after DC cycle, fix the
issue.

Check redfish interface https://ip/redfish/v1/Systems/system
UUID shows like "UUID": "ffffffff-ffff-ffffffff-ffffffffffff"
Then do a DC cycle, after DC cycle, the UUID in redfish interface is still
"UUID": "ffffffff-ffff-ffffffff-ffffffffffff"
