pktgen: Fix position of ip and udp header
skb_set_network_header() expects an offset based on the data pointer
whereas skb_tail_offset() also includes the headroom. This resulted
in the ip header being written in a wrong location.
Use return values of skb_put() directly and rely on skb->len to
set mac, network, and transport header.
