[PATCH 1/2] wined3d: Create the backbuffer rendertarget view only after calling adapter_init_3d().

[Henri Verbeet]

Otherwise we may not be able to acquire a context to create the view. In
practice, this is only an issue for d3d9 and earlier in combination with the
Vulkan backend.

Direct3D 9 and earlier applications don't generally work with the Vulkan
backend, mainly due to lack of shader model 1-3 support. Still, this may be
enough for applications that only use these earlier Direct3D versions for e.g.
capability queries.
