Yichong Chen bda6a7308e bpftool: Fix vmlinux BTF leak in cgroup commands ... bpftool cgroup show and tree call libbpf_find_kernel_btf() to resolve attach_btf names, but never release the returned BTF object. For cgroup tree, do_show_tree_fn() is called once for each cgroup visited by nftw(). When more than one cgroup has attached programs, each callback overwrites btf_vmlinux with a new object and loses the previous allocation. Load vmlinux BTF only once during a tree walk and release it when cgroup show or tree completes. Reset btf_vmlinux_id at the same time so batch mode starts with clean state.
