st/nine: NineDevice9_Clear skip fastpath for bigger depth-buffers 

This adds an additional check to make sure the bound depth-buffer doesn't
exceed the rendertarget size when clearing depth and color buffer at once.
D3D9 clears only a rectangle with the same dimensions as the viewport, leaving
other parts of the depth-buffer intact.

This fixes failing WINE test visual.c:depth_buffer_test()
