CreateDCA patch

[Andreas Mohr]

Hi all,

CreateDCA should return failure if both driver and device are NULL
instead of just crashing.
Fixes *one* problem with Microsoft Works.
(in other words: "Microsoft Works doesn't" ;-)

This is a patch that implements what has been discussed years ago on
c.e.m.w. already.
