Ruidong Tian 2d98dbb4c9 perf scripts python arm-cs-trace-disasm.py: Do not ignore disam first sample 
arm-cs-trace-disasm ignore disam the first branch sample, For example as
follow, the instructions beteween 0x0000ffffae878750 and
0x0000ffffae878754 is lose:

  ARM CoreSight Trace Data Assembler Dump
  Event type: branches:uH
  Sample = { cpu: 0000 addr: 0x0000ffffae878750 phys_addr: 0x0000000000000000 ip: 0x0000000000000000 pid: 4003489 tid: 4003489 period: 1 time: 26765151766034 }
  Event type: branches:uH
  Sample = { cpu: 0000 addr: 0x0000000000000000 phys_addr: 0x0000000000000000 ip: 0x0000ffffae878754 pid: 4003489 tid: 4003489 period: 1 time: 26765151766034 }

Initialize cpu_data earlier to fix it:
