Thanks, I missed that.

It is not a pure wording fix, but it corrects an overly specific error
description that does not hold any more in the case of Landlock ABI version 4.

With the introduction of Landlock ABI v4, attr->handled_access_fs is not
technically accurate any more, but it can also be attr->handled_access_net(!)
now, in the case where someone uses these new networking features.  So I made
the phrasing a bit more general to cover both.

Sounds good.

Thanks for the review!
