Arnaldo Carvalho de Melo 54ef362e4d perf callchain: Use zfree() to avoid possibly accessing dangling pointers ... When freeing a->b it is good practice to set a->b to NULL using zfree(&a->b) so that when we have a bug where a reference to a freed 'a' pointer is kept somewhere, we can more quickly cause a segfault if some code tries to use a->b. Convert one such case in the callchain code.
