ddraw: Return the appropriate identifier for GetDeviceIdentifier.

Hi WineBuG, it looks like that application uses DirectDrawEnumerateA instead of
DirectDrawEnumerateExA.  I just ran some tests and this is what I see:

**DirectDrawEnumerateA**
1) Primary Display Driver
**DirectDrawEnumerateExA**
1) Primary Display Driver
2) Intel(R) HD Graphics

This matches Wine (except that we report "DirectDraw HAL" instead of "Primary
Display Driver" for compatibility reasons).  So, this is bug is pretty much
fixed.  However, downloading your application and giving it a try appears to
display:
Primary Display Driver (Intel(R) HD Graphics)
where Wine reports:
DirectDraw HAL (DirectDraw HAL)

Investigating this shows that the problem is in GetDeviceIdentifier when it is
_not_ passed the DDGDI_GETHOSTIDENTIFIER flag.  I've attached a patch that
corrects this information, if you could please give that a try (and open a new
bug to report the results) then I would really appreciate it.
