[DCCP]: Perform SHUT_RD and SHUT_WR on receiving close
This patch performs two changes: 1) Close the write-end in addition to the read-end when a fin-like segment (Close or CloseReq) is received by DCCP. This accounts for the fact that DCCP, in contrast to TCP, does not have a half-close. RFC 4340 says in this respect that when a fin-like segment has been sent there is no guarantee at all that any further data will be processed. Thus this patch performs SHUT_WR in addition to the SHUT_RD when a fin-like segment is encountered. 2) Minor change: I noted that code appears twice in different places and think it makes sense to put this into a self-contained function (dccp_enqueue()).
