This looks like another network-namespace regression.
icmp_send() does:

        net = rt->u.dst.dev->nd_net;

The bridge netfilter code attaches a fake dst_entry to the
skb which has dev == NULL when passing it to IPv4 netfilter.

Pavel, do you have a better ideas for fixing this than
instantiating a dst_entry in br_netfilter.c for every
device (or at least for every namespace)?
