kconfig: fix savedefconfig with choice marked optional
savedefconfig failed to save the correct minimal config when it encountered a choice marked optional. Consider following minimal configuration: $cat Kconfig choice prompt "choice" optional config A bool "a" config B bool "b" endchoice $cat .config | grep -v ^# CONFIG_A=y $conf --savedefconfig=defconfig Kconfig would before this fix result in an empty file, because kconfig would assume that CONFIG_A=y is a default value. But because the choice is optional the default is that both A and B are =n. Fix so we handle optional choices correct.
