I wouldn't do anything concerning it.
I wouldn't take it away, I wouldn't trade it out for a magic item that does the exact same thing, heck I wouldn't even mention it.
And if I did mention it? I'd do it in character via an NPC at some appropriate point - as in "You can see in the dark? Huh, I've never met one of your kind that could do that before."
This particular DB just happens to have darkvision.
Going forward though we'd correct the error no future DB characters would have it.
