perf annotate: Use zfree() to reduce chances of use after free

Browse source

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 include the missing linux/zalloc.h header directive.
