Florian Westphal 10f0af5234 netfilter: tproxy: bail out if IP has been disabled on the device
[ Upstream commit 21a673bddc8fd4873c370caf9ae70ffc6d47e8d3 ]

syzbot reports:
general protection fault, probably for non-canonical address 0xdffffc0000000003: 0000 [#1] PREEMPT SMP KASAN PTI
KASAN: null-ptr-deref in range [0x0000000000000018-0x000000000000001f]

__in_dev_get_rcu() can return NULL, so check for this.
