[ Upstream commit 73534617dfa3c4cd95fe5ffaeff5315e9ffc2de6 ]
The btf__load_from_kernel_by_id() only takes one arg, not two.
Committer notes:
I tested it just with an older libbpf, one where btf__load_from_kernel_by_id() wasn't introduced yet.
A test with a newer dynamic libbpf would fail because the btf__load_from_kernel_by_id() is there, but takes just one arg.
