perf parse-events: Use zfree() to reduce chances of use after free
Do defensive programming by using zfree() to initialize freed pointers
to NULL, so that eventual use after free result in a NULL pointer deref
instead of more subtle behaviour.
Also remove one NULL test before free(), as it accepts a NULL arg and we
get one line shaved not doing it explicitely.
