Jakub Kicinski 75e2c86c7b net: netlink: catch attempts to send empty messages

syzbot can figure out a way to redirect a netlink message to a tap.
Sending empty skbs to devices is not valid and we end up hitting
a skb_assert_len() in __dev_queue_xmit().

Make catching these mistakes easier, assert the skb size directly
in netlink core.
