It simplifies waiting for the CCID module to signal that a packet
is ready to be sent. Other simplifications flow on from this such as
removing constants.
As a result of this EAGAIN is not returned any more by dccp_wait_for_ccid
(which would otherwise lead to unnecessarily discarding the packet in
dccp_write_xmit).
