Xin Long 3c6e5f2f5e sctp: reinit stream if stream outcnt has been change by sinit in sendmsg 
[ Upstream commit 625637bf4a ]

After introducing sctp_stream structure, sctp uses stream->outcnt as the
out stream nums instead of c.sinit_num_ostreams.

However when users use sinit in cmsg, it only updates c.sinit_num_ostreams
in sctp_sendmsg. At that moment, stream->outcnt is still using previous
value. If it's value is not updated, the sinit_num_ostreams of sinit could
not really work.

This patch is to fix it by updating stream->outcnt and reiniting stream
if stream outcnt has been change by sinit in sendmsg.

Fixes: a83863174a ("sctp: prepare asoc stream for stream reconf")
