dccp: fix memory leak during tear-down of unsuccessful connection request

[ Upstream commit 72ef9c41 ]

This patch fixes a memory leak, which happens if the connection request
is not fulfilled between parsing the DCCP options and handling the SYN
(because e.g. the backlog is full), because we forgot to free the
list of ack vectors.
