[DCCP]: Fix skb leak in dccp_sendmsg

		goto out_discard;

	/*

	 * XXX we don't use sk_write_queue, so just discard the packet.

	 *     Current plan however is to _use_ sk_write_queue with

	 *     an algorith similar to tcp_sendmsg, where the main difference

	 *     is that in DCCP we have to respect packet boundaries, so

	 *     no coalescing of skbs.

	 *

	 *     This bug was _quickly_ found & fixed by just looking at an OSTRA

	 *     generated callgraph 8) -acme
