vxlan: advertise link netns in fdb messages
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.
Fixes: 193523bf9373 ("vxlan: advertise netns of vxlan dev in fdb msg")
