[PATCH -stable-3.9 14/15] netfilter: nf_nat_sip: fix mangling

[Pablo Neira Ayuso <pablo@netfilter.org>]

From: Balazs Peter Odor <balazs@obiserver.hu>

In (b20ab9c netfilter: nf_ct_helper: better logging for dropped packets)
there were some missing brackets around the logging information, thus
always returning drop.
