Subject: [PATCH AUTOSEL 5.4 06/13] netfilter: nfnetlink_log: silence bogus compiler warning

From: Florian Westphal <fw@...len.de>

[ Upstream commit 2e1d175410972285333193837a4250a74cd472e6 ]

net/netfilter/nfnetlink_log.c:800:18: warning: variable 'ctinfo' is uninitialized

The warning is bogus, the variable is only used if ct is non-NULL and
always initialised in that case.  Init to 0 too to silence this.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202309100514.ndBFebXN-lkp@intel.com/
