ddraw/tests: Don't crash after a failed CreateSurface() call.

[Francois Gouget]

So there are a number of CreateSurface() calls that fail and these are 
causing the tests to crash. For instance for ddraw2:
http://test.winehq.org/data/tests/ddraw:ddraw2.html

Is there a way to check what surface types are supported? 
create_device() calls EnumDevices() but finding a match clearly does not 
guarantee we'll be able to create a surface given the error we get there 
(but presumably that check was more for the following CreateDevice() 
call). I tried using EnumSurfaces() but without much luck. I'm also a 
bit worried that DDENUMSURFACES_MATCH is not used anywhere in Wine (*).

Alternatively we can just react to failing CreateSurface() calls and 
clean up + abort a bit like is done in the following patch.

(*) Also the DDENUMSURFACES_{SEARCH,MATCH}TYPE macros found in 
    dlls/ddraw/ddraw.c are not used anymore since c8901d6f.
