Cong Wang e804124390 sit: update dev->needed_headroom in ipip6_tunnel_bind_dev() 
[ Upstream commit c88f8d5cd9 ]

When a tunnel device is bound with the underlying device, its
dev->needed_headroom needs to be updated properly. IPv4 tunnels
already do the same in ip_tunnel_bind_dev(). Otherwise we may
not have enough header room for skb, especially after commit
b17f709a24 ("gue: TX support for using remote checksum offload option").

Fixes: 32b8a8e59c ("sit: add IPv4 over IPv4 support")
