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.
