[103/119] netfilter: xt_connlimit: fix regression caused by zero family value

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Jan Engelhardt <jengelh@xxxxxxxxxx>

commit 539054a8fa5141c9a4e9ac6a86d249e3f2bdef45 upstream.

Commit v2.6.28-rc1~717^2~109^2~2 was slightly incomplete; not all
instances of par->match->family were changed to par->family.
