sit: update dev->needed_headroom in ipip6_tunnel_bind_dev()
[ Upstream commit c88f8d5cd95fd039cff95d682b8e71100c001df0 ]
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
b17f709a2401 ("gue: TX support for using remote checksum offload option").
Fixes: 32b8a8e59c9c ("sit: add IPv4 over IPv4 support")
