net: veth: fix packet segmentation in veth_convert_skb_to_xdp_buff
Based on the previous allocated packet, page_offset can be not null
in veth_convert_skb_to_xdp_buff routine.
Take into account page fragment offset during the skb paged area copy
in veth_convert_skb_to_xdp_buff().
Fixes: 2d0de67da51a ("net: veth: use newly added page pool API for veth with xdp")
