Masahiro Yamada 0cbe3ac439 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.
