IPv4: early demux can return an error code
[ Upstream commit 7487449c86c65202b3b725c4524cb48dd65e4e6f ]
Currently no error is emitted, but this infrastructure will
used by the next patch to allow source address validation
for mcast sockets.
Since early demux can do a route lookup and an ipv4 route
lookup can return an error code this is consistent with the
current ipv4 route infrastructure.
