ip_tunnel: embed hash list head
The IP tunnel hash heads can be embedded in the per-net structure since it is a fixed size. Reduce the size so that the total structure fits in a page size. The original size was overly large, even NETDEV_HASHBITS is only 8 bits! Also, add some white space for readability.
