When perf report --children resorts output fields, it tries to put caller above the callee. But this was only meaningful for a same thread and doing this requires callchain enabled. So fix its check before comparing the callchain depth. This also changes the hist accumulation tests: In test 3, xmalloc in bash thread should be above than other perf threads due to alphabetical order of comm string. Also it's under page_fault in bash thread since alphabetical order of dso name. The sys_perf_event_open in perf thread is put on the last line since it's self overhead is 0. In test 4, the sys_perf_event_open is put above other perf entries that have same children overhead since its callchain depth is smaller.
