tcp/dccp: Remove inet_connection_sock_af_ops.addr2sockaddr().

inet_connection_sock_af_ops.addr2sockaddr() hasn't been used at all
in the git era.

  $ git grep addr2sockaddr $(git rev-list HEAD | tail -n 1)

Let's remove it.

Note that there was a 4 bytes hole after sockaddr_len and now it's
6 bytes, so the binary layout is not changed.
