Don't cleanup NDP state when enabling forwarding
...to match linux behaviour:
```
$ sudo sysctl net.ipv6.conf.eno1.forwarding
net.ipv6.conf.eno1.forwarding = 0
$ ip addr list dev eno1
2: eno1: <...> ...

$ sudo sysctl -w "net.ipv6.conf.all.forwarding=1"
net.ipv6.conf.all.forwarding = 1
$ sudo sysctl net.ipv6.conf.eno1.forwarding
net.ipv6.conf.eno1.forwarding = 1
$ ip addr list dev eno1
