http: fix memory leak in fetch_and_setup_pack_index()
Inside the function `fetch_and_setup_pack_index()`, when the pack obtained using `parse_pack_index()` fails to be verified by `verify_pack_index()`, the function returns without closing and freeing said pack. Fix this by calling `close_pack_index()` to munmap the index file for the leaking pack (which might have been mmapped by `fetch_pack_index()` or `verify_pack_index()`), and then free it, when the verification fails.
