[NETNS]: Add namespace for ICMP replying code.
All needed API is done, the namespace is available when required from the device on the DST entry from the incoming packet. So, just replace init_net with proper namespace. Other protocols will follow. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
