perf cs-etm: Generate branch sample when receiving a CS_ETM_TRACE_ON packet
If one CS_ETM_TRACE_ON packet is inserted, we miss to generate branch
sample for the previous CS_ETM_RANGE packet.
This patch is to generate branch sample when receiving a CS_ETM_TRACE_ON
packet, so this can save complete info for the previous CS_ETM_RANGE
packet just before CS_ETM_TRACE_ON packet.
