Jiri Olsa f76d8507d2 bpftool: Fix pretty print dump for maps without BTF loaded ...

The commit e5043894b2 ("bpftool: Use libbpf_get_error() to check error")
fails to dump map without BTF loaded in pretty mode (-p option).

Fixing this by making sure get_map_kv_btf won't fail in case there's
no BTF available for the map.
