John Fastabend 850184e700 bpf, xdp: Update devmap comments to reflect napi/rcu usage ...

commit 42a84a8cd0ff0cbff5a4595e1304c4567a30267d upstream.

Now that we rely on synchronize_rcu and call_rcu waiting to
exit perempt-disable regions (NAPI) lets update the comments
to reflect this.

Fixes: 0536b85239b84 ("xdp: Simplify devmap cleanup")
