pktgen: bug fix in transmission headers with frags=0
(bug introduced by commit 26ad787962ef84677a48c560
(pktgen: speedup fragmented skbs)
The headers of pktgen were incorrectly added in a pktgen packet
without frags (frags=0). There was an offset in the pktgen headers.
The cause was in reusing the pgh variable as a return variable in skb_put
when adding the payload to the skb.
