ip_frag: fix IP reassembly regression

After changing pkt[0] to pkt[], the example IP reassembly is not working.
It's weird because this change is fine. There should be no difference
between them.
As a workaround, revert this change.

Fixes: 347a1e037fd3 ("lib: use C99 syntax for zero-size arrays")
