kconfig: qconf: remove wrong ConfigList::firstChild()
This function returns the first child object, but the returned pointer is not compatible with (ConfigItem *). Commit cc1c08edccaf ("kconfig: qconf: don't show goback button on splitMode") uncovered this issue because using the pointer from this function would make qconf crash. (https://lkml.org/lkml/2020/7/18/411) This function does not work. Remove. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
