2017-02-09sctp: streams should be recovered when it fails to send request.Xin Long1-2/+17
Now when sending stream reset request, it closes the streams to block further xmit of data until this request is completed, then calls sctp_send_reconf to send the chunk. But if sctp_send_reconf returns err, and it doesn't recover the streams' states back, which means the request chunk would not be queued and sent, so the asoc will get stuck, streams are closed and no packet is even queued. This patch is to fix it by recovering the streams' states when it fails to send the request, it is also to fix a return value.
