[DCCP]: Use `unsigned' for packet lengths
This patch implements a suggestion by Ian McDonald and 1) Avoids tests against negative packet lengths by using unsigned int for packet payload lengths in the CCID send_packet()/packet_sent() routines 2) As a consequence, it removes an now unnecessary test with regard to `len > 0' in ccid3_hc_tx_packet_sent: that condition is always true, since * negative packet lengths are avoided * ccid3_hc_tx_send_packet flags an error whenever the payload length is 0. As a consequence, ccid3_hc_tx_packet_sent is never called as all errors returned by ccid_hc_tx_send_packet are caught in dccp_write_xmit 3) Removes the third argument of ccid_hc_tx_send_packet (the `len' parameter), since it is currently always set to skb->len. The code is updated with regard to this parameter change.
