Both the INQUIRY handling and the XCOPY implementation provide functions to generate an NAA designator. In addition, these functions are poorly named: - spc_parse_naa_6h_vendor_specific() - target_xcopy_gen_naa_ieee() Introduce a common NAA 6 designator generation function, spc_gen_naa_6h_vendor_specific().
