ipv6: don't use tw net when accounting for recycled tw
We already have a valid net in that place, but this is not just a cleanup - the tw pointer can be NULL there sometimes, thus causing an oops in NET_NS=y case. The same place in ipv4 code already works correctly using existing net, rather than tw's one. The bug exists since 2.6.27. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
