[PATCH 6.18.y 1/2] netfilter: nf_conntrack_sip: remove net variable shadowing

[Sasha Levin <sashal@kernel.org>]

From: Florian Westphal <fw@strlen.de>

[ Upstream commit 7970d6aaf710db166de98c5356a260089896fae5 ]

net is already set, derived from nf_conn.
I don't see how the device could be living in a different netns
than the conntrack entry.

Remove the extra variable and re-use existing one.
