commit ad106a26aef3a95ac7ca88d033b431661ba346ce upstream. When syncing, it may be that branch packet generation is not enabled at that point, in which case there will not immediately be a control-flow packet, so some packets before a control flow packet turns up, get ignored. However, the decoder is in sync as soon as a PSB is found, so the state should be set accordingly.
