[DCCP]: Remove redundant statements in init_sequence (ISS)
This patch removes the following redundancies:
1) The test skb->protocol == htons(ETH_P_IPV6) in dccp_v6_init_sequence
is always true since
* dccp_v6_conn_request() is the only calling function
* dccp_v6_conn_request() redirects all skb's with ETH_P_IP to
dccp_v4_conn_request()
2) The first argument, `struct sock *sk', of dccp_v{4,6}_init_sequence()
is never used.
(This is similar for tcp_v{4,6}_init_sequence, an analogous patch has been
submitted to netdev and merged.)
By the way - are the `sport' / `dport' arguments in the right order?
I have made them consistent among calls but they seem to be in the
reverse order.
