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

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

From: Chad Hanson <chanson@trustedcs.com>

commit 46d01d63221c3508421dd72ff9c879f61053cffc upstream.

Fix a broken networking check. Return an error if peer recv fails.  If
secmark is active and the packet recv succeeds the peer recv error is
ignored.
