[NETNS][TCP]: Register /proc/net/tcp in a namespace.
After the commit f40c8174d3c21bf178283f3ef3aa8c7bf238fdec ([NETNS][IPV4] tcp - make proc handle the network namespaces) it is now possible to make this file present in newly created namespaces. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
