fix warning

warning: 'ltc_asn1_type {aka enum ltc_asn1_type_}' is promoted to 'int' when passed through '...'
        type = va_arg(args, ltc_asn1_type);
note: (so you should pass 'int' not 'ltc_asn1_type {aka enum ltc_asn1_type_}' to 'va_arg')
note: if this code is reached, the program will abort
