ipv4: Disallow non-namespace aware protocols to register.
All in-tree ipv4 protocol implementations are now namespace aware. Therefore all the run-time checks are superfluous. Reject registry of any non-namespace aware ipv4 protocol. Eventually we'll remove prot->netns_ok and this registry time check as well. Signed-off-by: David S. Miller <davem@davemloft.net>
