Realising the following call pattern,
* first dccp_entail() is called to enqueue a new skb and
* then skb_clone() is called to transmit a clone of that skb,
this patch integrates both interrelated steps into dccp_entail().
Note: the return value of skb_clone is not checked. It may be an idea to add a
warning if this occurs. In both instances, however, a timer is set for
retransmission, so that cloning is re-tried via dccp_retransmit_skb().
