Say a user reuse map fd after creating a map manually and set the pin_path, then load the object via libbpf. In libbpf bpf_object__create_maps(), bpf_object__reuse_map() will return 0 if there is no pinned map in map->pin_path. Then after checking if map fd exist, we should also check if pin_path was set and do bpf_map__pin() instead of continue the loop. Fix it by creating map if fd not exist and continue checking pin_path after that.
