Ian Rogers d7ba60a4e5 perf header: Avoid out-of-bounds read 
intel-pt tests were failing:

  -- Test virtual LBR ---
  Linux
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.126 MB /tmp/perf-test-intel-pt-sh.FW57CXnCqQ/test-perf.data ]
  Failed with virtual lbr
  ...
  ```

  The root cause is an out-of-bounds read in header (where maxbrstack.py
  is from test_intel_pt.sh):
  ```
  $ perf --no-pager script --itrace=L -s maxbrstack.py

Avoid the out-of-bounds read checking for the leader. Leave the 'nr'
check intact as nr will be 0 or the counting down and evsel be a group
member.
