perf tools: Fix report -F dso_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 dso_from
perf: Segmentation fault
Checking that hist_entry::branch_info is valid and display "N/A" string
in snprint callback if it's not.
