[PATCH 2/2] parse-options.c: use "enum parse_opt_result" for parse_nodash_opt()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the parse_nodash_opt() function to use "enum
parse_opt_result". In 352e761388b (parse-options.[ch]: consistently
use "enum parse_opt_result", 2021-10-08) its only caller
parse_options_step() started using that return type, and the
get_value() which will be called and return from it uses the same
enum.

Let's do the same here so that this function always returns an "enum
parse_opt_result" value.
