[PATCH v3 5/8] Free the path_lists used to find non-local tags in git-fetch

["Shawn O. Pearce" <spearce@spearce.org>]

To support calling find_non_local_tags() more than once in a single
git-fetch process we need the existing_refs to be stack-allocated
so it resets on the second call.  We also should free the path
lists to avoid unnecessary memory leaking.
