wined3d: NP2 coordinate adjustment is a vertex operation. 

When a sampler is changed and unconditional NP2 textures are not
supported, the texture matrix may need adjustment. The sampler state
function checks for that, and calls the texture transform setting
function in that case. However, samplers are a misc state, and the
texture transform flags a vertex state.  Thus split up the code and
move the matrix changes to the vertex side.
