Whether you WARN or not, any remaining item is going to be leaked. I'd
go with WARN (or maybe DEBUG_NET_WARN_ON_ONCE) and free remaining
items. It should never happen but seems easy to deal with, so why not
handle it?

This said, I have a question regarding DEBUG_NET_WARN_ON_ONCE: it prints
something only if CONFIG_DEBUG_NET is enabled.
Is this the case on standard desktop/server distribution? Otherwise how are
we going to get reports from users?

A bit tangential, but:
