kconfig: remove dead code in conf_askvalue()
conf_askvalue() is only called for oldconfig, syncconfig, and oldaskconfig. If it is called for other cases, it is a bug. So, the code after the switch statement is unreachable. Remove the dead code, and clean up the switch statement. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
