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.
