[PATCH 4.19 021/191] bpf: Fix comment for helper bpf_current_task_under_cgroup()

[Greg Kroah-Hartman]

From: Song Liu <songliubraving@xxxxxx>

commit 1aef5b4391f0c75c0a1523706a7b0311846ee12f upstream.

This should be "current" not "skb".

Fixes: c6b5fb8690fa ("bpf: add documentation for eBPF helpers (42-50)")
