bpf: Remove !func_info and !line_info check from test_btf and bpftool
kernel can provide the func_info and line_info even it fails the btf_dump_raw_ok() test because they don't contain kernel address. This patch removes the corresponding '== 0' test. Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
