We still need to find the item even if the caller is not interested, to
know if we should have returned -ENOENT, so I think it's just a matter
of style.

I did have the API to return the pointer earlier in development, but it
didn't look good and uniform. But in the final piece, that was picked
up, I think it makes more sense (and looks better) to do it this way.

How sneaky of you, then we need to approve those patches before we
add new consumers of this API...
