[precise][sru][pull-request] fix for lp#1256988

[Chris J Arges]

BugLink: http://bugs.launchpad.net/bugs/1256988

SRU Justification:

[Impact]
* When restoring an iptable in a network namespace, if the network
namespace is deleted the kernel crashes.

[Test Case]
$ sudo -s
# ip netns add foobar
# ip netns exec foobar iptables -A OUTPUT -m recent --rcheck --rsource
# ip netns del foobar

[Regression Potential]
* The following patches fix the issue:
665e205c1
32263dd1b

In addition this patch is required to fix a potential regression
introduced by the original fix:
https://git.kernel.org/cgit/linux/kernel/git/pablo/nf.git/commit/?id=b4ef4ce09308955d1aa54a289c0162607b3aa16c

Two are upstream linux patches, the last it still in the netfilter
upstream tree.
