[SK_BUFF]: More skb_put related conversions to skb_reset_transport_header
This is similar to the skb_reset_network_header(), i.e. at the point we reset the transport header pointer/offset skb->tail is equal to skb->data. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
