virtio: Net header needs hdr_len
It's far easier to deal with packets if we don't have to parse the packet to figure out the header length to know how much to pull into the skb data. Add the field to the virtio_net_hdr struct (and fix the spaces that somehow crept in there). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
