compat: udp_tunnel: don't take reference to non-init namespace

The comment to sk_change_net is instructive:

  Kernel sockets, f.e. rtnl or icmp_socket, are a part of a namespace.
  They should not hold a reference to a namespace in order to allow
  to stop it.
  Sockets after sk_change_net should be released using sk_release_kernel

We weren't following these rules before, and were instead using
__sock_create, which means we kept a reference to the namespace, which
in turn meant that interfaces were not cleaned up on namespace
exit.
