Return the cgroup v2 id of the socket sk.
sk must be a non-NULL pointer to a socket, e.g. one returned from bpf_sk_lookup_xxx(), bpf_sk_fullsock(), etc. The format of returned id is same as in bpf_skb_cgroup_id().
This helper is available only if the kernel was compiled with the CONFIG_SOCK_CGROUP_DATA configuration option.

The id is returned or 0 in case the id could not be retrieved.
