Don't try to translate NULL in GetConfigOptionByNum().
Noticed via -fsanitize=undefined. Introduced when a few columns in GetConfigOptionByNum() / pg_settings started to be translated in 72be8c29a / PG 12. Backpatch to all affected branches, for the same reasons as 46ab07ffda9. Discussion: https://postgr.es/m/20220323173537.ll7klrglnp4gn2um@alap3.anarazel.de Backpatch: 12-
