When GSO tunnel is negotiated virtio_net_hdr_tnl_from_skb() tries to
initialize the tunnel metadata but forget to zero unused rxhash
fields. This may leak information to another side. Fixing this by
zeroing the unused hash fields.

Fixes: a2fb4bc4e2a6a ("net: implement virtio helpers to handle UDP GSO tunneling")x

I just spotted this has an unnecessary trailing 'x'. Will post V2.
