r600/sfn: update readports before trying to schedule group instrutions

Browse source 
We only do minimal checks to ensure that copy propagation doesn't break
the readport setup, but we don't update the groups readport setup. So
before scheduling the group do this update. Also check the readport
constellation when scheduling a group is finished.
