netfilter: nf_log: do not assume ethernet header in netdev family
In netdev family, we will handle non ethernet packets, so using
eth_hdr(skb)->h_proto is incorrect.
Meanwhile, we can use socket(AF_PACKET...) to sending packets, so
skb->protocol is not always set in bridge family.
Add an extra parameter into nf_log_l2packet to solve this issue.
Fixes: 1fddf4bad0ac ("netfilter: nf_log: add packet logging for netdev family")
