[PATCH v3 3/8] diff.c: do not pass diff options as keydata to hashmap

When we initialize the hashmap, we give it a pointer to the diff_options, which it then passes along to each call of the hashmap_cmp_fn function. There's no need to pass it a second time as the "keydata" parameter, and our comparison functions never look at keydata.

This was a mistake left over from an earlier round of 2e2d5ac184 (diff.c: color moved lines differently, 2017-06-30), before hashmap learned to pass the data pointer for us.
