Jiri Olsa 1b9e97a2a9 perf tools: Fix report -F symbol_from for data without branch info 
The branch field sorting code assumes hist_entry::branch_info is
allocated, which is wrong and following perf session ends up with report
segfault.

  $ perf record ls
  $ perf report -F symbol_from
  perf: Segmentation fault

Checking that hist_entry::branch_info is valid and display "N/A" string
in snprint callback if it's not.
