[PATCH v3 6/6] perf cs-etm: Synchronize instruction sample with the thread stack

The synthesized flow use 'tidq->packet' for instruction samples; on the other hand, 'tidp->prev_packet' is used to generate the thread stack and the branch samples, this results in the instruction samples using one packet ahead than thread stack and branch samples ('tidp->prev_packet' vs 'tidq->pac
