Stefano Brivio 24fc79798b ip_tunnel: Clamp MTU to bounds on new link 
Otherwise, it's possible to specify invalid MTU values directly
on creation of a link (via 'ip link add'). This is already
prevented on subsequent MTU changes by commit b96f9afee4
("ipv4/6: use core net MTU range checking").

Fixes: c544193214 ("GRE: Refactor GRE tunneling code.")
