ip6_tunnel: fix IFLA_MTU ignored on NEWLINK
[ Upstream commit a6aa80446234ec0ad38eecdb8efc59e91daae565 ]
Commit 128bb975dc3c ("ip6_gre: init dev->mtu and dev->hard_header_len
correctly") fixed IFLA_MTU ignored on NEWLINK for ip6_gre. The same
mtu fix is also needed for ip6_tunnel.
Note that dev->hard_header_len setting for ip6_tunnel works fine,
no need to fix it.
