tun: Don't copy 16byte IPv6 address to 'struct in_addr'
The 'struct tun' curently only has an in_addr (v4-only) member to
store the address of the tun device, so let's not attempt to store
an IPv6 address in it.
FIXME: This entire code needs an overhaul. The assumption that there's
only one address, and only either v6 or v4 is broken to begin with.
