Previous commit is based on a wrong assumption, fdb messages are always sent into the netns where the interface stands (see vxlan_fdb_notify()). These fdb messages doesn't embed the rtnl attribute IFLA_LINK_NETNSID, thus we need to add it (useful to interpret NDA_IFINDEX or NDA_DST for example). Note also that vxlan_nlmsg_size() was not updated.
