batman-adv: tp_meter: initialize dec_cwnd explicitly

Browse source

When batadv_tp_update_cwnd() is called, dec_cwnd is increased. But dec_cwnd
is only initialixed (to 0) when a duplicate Ack was received or when cwnd
is below the ss_threshold.

Just initialize the cwnd during the initialization to avoid any potential
access of uninitialized data.
