clean: remove unnecessary variable

The variable `matches` used to hold the return of a `dir_path_match()` call that was removed in 95c11ecc73 ("Fix error-prone fill_directory() API; make it only return matches", 2020-04-01). Now `matches` will always hold 0, which is the value it's initialized with; and the condition `matches != MATCHED_EXACTLY` will always evaluate to true. So let's remove this unnecessary variable. Interestingly, it seems that `matches != MATCHED_EXACTLY` was already unnecessary before 95c11ecc73. That's because `remove_directories` is always set to 1 when we have pathspecs; So, in the condition `!remove_directories && matches != MATCHED_EXACTLY`, we would either: - have pathspecs (or have been given `-d`) and ignore `matches` because `remove_directories` is 1; or - not have pathspecs (nor `-d`) and end up just checking that `0 != MATCHED_EXACTLY`, as `matches` would never get reassigned after its zero initialization (because there is no pathspec to match).
