parse-options.c: use exhaustive "case" arms for "enum parse_opt_result"
Change the "default" case in parse_options() that handles the return value of parse_options_step() to simply have a "case" arm for PARSE_OPT_UNKNOWN, instead of leaving it to a comment. This means the compiler can warn us about any missing case arms. This adjusts code added in ff43ec3e2d2 (parse-opt: create parse_options_step., 2008-06-23), given its age it may pre-date the existence (or widespread use) of this coding style, which we've since adopted more widely.
