The garbage collection function receive the dst_ops structure as
parameter. This is useful for the next incoming patchset because
it will need the dst_ops (there will be several instances) and
the network namespace pointer (contained in the dst_ops).
The protocols which do not take care of the namespaces will not
be impacted by this change (expect for the function signature),
they do just ignore the parameter.
