combine-diff: combine_diff_path.len is not needed anymore

Browse Source 
The field was used in order to speed-up name comparison and also to
mark removed paths by setting it to 0.

Because the updated code does significantly less strcmp and also
just removes paths from the list and free right after we know a path
will not be needed, it is not needed anymore.
