[PATCH] wined3d: use surface_prepare_texture for surface allocation in read_from_framebuffer_texture

[Roderick Colenbrander]

Right now read_from_framebuffer_texture calls surface_allocate_surface but this call doesn't
set conversion flags which caused bug 22356. The use of surface_prepare_texture fixes this.
