Andrii Nakryiko f08c18e083 libbpf: don't rely on map->fd as an indicator of map being created
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().
