[PATCH 2/3] app/test_bpf: don't print eBPF program if NULL

[Ananyev, Konstantin]

> If conversion of cBPF to eBPF fails (in rte_bpf_convert)
> then the test should not try and print the result.
> 
> Coverity issue: 373661
> Fixes: 2eccf6afbea9 ("bpf: add function to convert classic BPF to DPDK BPF")
