Stefano Brivio b57f0fe6e3 vti6: Fix dev->max_mtu setting 
[ Upstream commit f8a554b4aa9686bb2c12f6bae516e58783289a03 ]

We shouldn't allow a tunnel to have IP_MAX_MTU as MTU, because
another IPv6 header is going on top of our packets. Without this
patch, we might end up building packets bigger than IP_MAX_MTU.

Fixes: b96f9afee4eb ("ipv4/6: use core net MTU range checking")
