Subject: [PATCH] netfilter: bridge: fix NULL deref in physin/out ifindex
 helpers

Might not have an outdev yet. We'll oops when iface goes down while skbs
are still nfqueue'd:

RIP: 0010:[<ffffffff81422a2f>]  [<ffffffff81422a2f>] dev_cmp+0x4f/0x80
nfqnl_rcv_dev_event+0xe2/0x150
notifier_call_chain+0x53/0xa0

Fixes: c737b7c4510026 ("netfilter: bridge: add helpers for fetching physin/outdev")
