[PATCH 1/6] kconfig: do not call check_conf() for olddefconfig

[Masahiro Yamada]

check_conf() traverses the menu tree, but it is completely no-op for
olddefconfig because the following if-else block does nothing.

    if (input_mode == listnewconfig) {
            ...
    } else if (input_mode != olddefconfig) {
            ...
    }

As the help message says, olddefconfig automatically sets new symbols
to their default value.  There is no room for manual intervention.
So, calling check_conf() for olddefconfig is odd in the first place.
Rather, olddefconfig belongs to the group of alldefconfig and defconfig.
