kconfig: remove k_invalid from expr_parse_string() return type
The only possibility of k_invalid being returned was when expr_parse_sting() parsed S_OTHER type symbol. This actually never happened, and this is even clearer since S_OTHER has gone. Clean up unreachable code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
