[wined3d] check for null vertex declaration

[Oliver Stieber]

Hi,
This patch check to see if the vertex declaration is
null before trying to reference it.

With this patch Pirates! should now be playable.

Enable shaders in wine, but select disable shaders in
pirates. Otherwise you will have some problems with
missing textures.

There's no support for VBO's get so turn the detail
setting right down. (With VBO's I can get about 30fps,
with all the setting up)
