[15/16] WineD3D: Select a proper texture unit in LockRect, and dirtify the state

[Stefan Dösinger]

Does not really belong to the other patches, but I stumbled uppon  
this. LockRect binds the texture to the selected texture unit. This  
patch selects unit 0 and marks sampler 0 dirty to force an update on  
the next draw.
