4.1-stable review patch. If anyone has any objections, please let me know.

------------------

From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>

commit 95dd8653de658143770cb0e55a58d2aab97c79d2 upstream.

We have to put back the references to the master conntrack and the expectation
that we just created, otherwise we'll leak them.
