WINED3D: Return D3DERR_INVALIDCALL when calling BeginStateBlock and already recording.

[H. Verbeet]

Calling BeginStateBlock while already recording should return
D3DERR_INVALIDCALL. Verified on w2k. Keeps the Battlefield 2 Demo from
crashing a little bit longer.

Changelog:
  - Return D3DERR_INVALIDCALL when calling BeginStateBlock and already
recording.
