Commit 6018e1f407cc ("bpf: implement numbers iterator") added the
BTF_TYPE_EMIT line that this patch is modifying. The struct btf_iter_num
doesn't exist, so only a forward declaration is emitted in BTF:
FWD 'btf_iter_num' fwd_kind=struct
Since that commit was probably hoping to ensure that struct bpf_iter_num
is emitted in vmlinux BTF, this patch changes it to the correct type.
This isn't marked "Fixes" because the extraneous btf_iter_num FWD wasn't
causing any issues that I noticed, aside from mild confusion when I
looked through the code.
