[NETNS]: icmp(v6)_sk should not pin a namespace.
So, change icmp(v6)_sk creation/disposal to the scheme used in the
netlink for rtnl, i.e. create a socket in the context of the init_net
and assign the namespace without getting a referrence later.
Also use sk_release_kernel instead of sock_release to properly destroy
such sockets.
