Arnaldo Carvalho de Melo b78854e5c0 perf probe: 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 'perf probe' codebase.
