Rather than having an addition write for each entry going through the
reorder library, it should be possible to change free function so that
it only frees entries based on the index values.

In fact, a better solution to having reorder_free just blindly free the
mbufs would be to have reorder_free hand them back to the application,
or allow reorder_free to fail if the reorder buffer is non-empty. Making
such a change would be an ABI break, though.
