ddraw: Verify that the surface is not a depth buffer in SetRenderTarget(). 

This check is even more inconsistent between versions. Notice how the v2
interface is particularly broken because it never AddRef()'s the new iface.
This check also seems to be the original source for the questionable behaviour
in d3d_device_set_render_target() of storing the new iface before checking the
result of the wined3d_device_set_render_target(). (In particular,
SetRenderTargetTest() in tests/d3d.c tests for this behavious.)
