sctp: fix stream update when processing dupcookie

Since commit 3dbcc105d556 ("sctp: alloc stream info when initializing
asoc"), stream and stream.out info are always alloced when creating
an asoc.

So it's not correct to check !asoc->stream before updating stream
info when processing dupcookie, but would be better to check asoc
state instead.

Fixes: 3dbcc105d556 ("sctp: alloc stream info when initializing asoc")
