[PATCH v3 bpf-next 2/9] libbpf: use explicit map reuse flag to skip map creation steps

[Andrii Nakryiko <andrii@xxxxxxxxxx>]

Instead of inferring whether map already point to previously
created/pinned BPF map (which user can specify with bpf_map__reuse_fd()) API),
use explicit map->reused flag that is set in such case.
