parse-options.c: use "enum parse_opt_result" for parse_nodash_opt()

Change the parse_nodash_opt() function to use "enum
parse_opt_result". In 352e761388 (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.

We could go for either PARSE_OPT_HELP (-2) or PARSE_OPT_ERROR (-1)
here. The reason we ended up with "-2" is that in code added in
07fe54db3c (parse-opt: do not print errors on unknown options, return
"-2" instead., 2008-06-23) we used that value in a meaningful way.

Then in 51a9949eda (parseopt: add PARSE_OPT_NODASH, 2009-05-07) the
use of "-2" was seemingly copy/pasted from parse_long_opt(), which was
the function immediately above the parse_nodash_opt() function added
in that commit.

Since we only care about whether the return value here is non-zero
let's use the more generic PARSE_OPT_ERROR.
