libata-scsi: set correct VERSION field for ZAC devices

Commit 856c466 ("libata: support device-managed ZAC devices") had the line that "bumps" the VERSION field in standard INQUIRY data removed. Add it back and claim SPC-5 version compatibility, which matches with the current version descriptor "SPC-5 (no version claimed)" that is used for ZAC devices.
