The skb_segment() function returns error pointers on error. It never
returns NULL.
Fixes: 76db8087c4c9 ("net: bpf: add a test for skb_segment in test_bpf module")

If you have a chance, please take this fix directly into your net-next tree
since it also contains the original commit 76db8087c4c9 ("net: bpf: add a
test for skb_segment in test_bpf module"), which is not in the bpf-next tree
at this point.
Thanks a lot,
Daniel
