Yinjun Zhang 28093e78e0 bpftool: Fix the error when lookup in no-btf maps ... [ Upstream commit edc21dc909 ] When reworking btf__get_from_id() in commit a19f93cfaf the error handling when calling bpf_btf_get_fd_by_id() changed. Before the rework if bpf_btf_get_fd_by_id() failed the error would not be propagated to callers of btf__get_from_id(), after the rework it is. This lead to a change in behavior in print_key_value() that now prints an error when trying to lookup keys in maps with no btf available. Fix this by following the way used in dumping maps to allow to look up keys in no-btf maps, by which it decides whether and where to get the btf info according to the btf value type.
