With the upcoming switch to preallocated placeholder FDs for maps, switch various getters/setter away from checking map->fd. Use map_is_created() helper that detect whether BPF map can be modified based on map->obj->loaded state, with special provision for maps set up with bpf_map__reuse_fd(). For backwards compatibility, we take map_is_created() into account in bpf_map__fd() getter as well. This way before bpf_object__load() phase bpf_map__fd() will always return -1, just as before the changes in subsequent patches adding stable map->fd placeholders. We also get rid of all internal uses of bpf_map__fd() getter, as it's more oriented for uses external to libbpf. The above map_is_created() check actually interferes with some of the internal uses, if map FD is fetched through bpf_map__fd().
