<div class='commit-subject'>sctp: streams should be recovered when it fails to send request.</div><div class='commit-msg'>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.
