MTU discovery fails with IPv6 sockets bound to IPv4 mapped address
pick up the IPv4 route for IPv4 mapped IPv6 address to get the correct
MTU and not any unrelated/inappropriate MTU from IPv6 routes. IPv4 mapped
IPv6 addresses are always handled by the IPv4 stack and MTU discovery
is solely handled with the IPv4 routing table.
