dlls/ddraw/executebuffer.c: silence compiler warnings

[Gerald Pfeifer]

Future versions of GCC will issue the following warnings in our default 
invocation, that is, without any additional options on top of what we 
already use:

executebuffer.c:230: warning: comparison between 'D3DRENDERSTATETYPE' and 'enum _D3DTRANSFORMSTATETYPE'
executebuffer.c:232: warning: comparison between 'D3DRENDERSTATETYPE' and 'enum _D3DTRANSFORMSTATETYPE'
executebuffer.c:234: warning: comparison between 'D3DRENDERSTATETYPE' and 'enum _D3DTRANSFORMSTATETYPE'

This patch addresses these.

Gerald


ChangeLog:
Add three missing casts to enum _D3DTRANSFORMSTATETYPE to 
IDirect3DExecuteBufferImpl_Execute().
