[DCCP]: Initialise write_xmit_timer also on passive sockets
The TX CCID needs the write_xmit_timer for delaying packet sends. Previously
this timer was only activated on active (connecting) sockets.
This patch initialises the write_xmit_timer in sync with the other timers, i.e.
the timer will be ready on any socket. This is used by applications with a
listening socket which start to stream after receiving an initiation by the
client. The write_xmit_timer is stopped when the application closes, as before.
Was tested to work and to remove the timer bug reported on dccp@vger.
Also moved timer initialisation into timer.c (static).
