[4/4] wined3d: Trigger frontbuffer update in surface_cpu_blt.

[Sebastian Lackner]

Fixes a regression introduced in ee17d7ba1b72b26baae90c1d5e2ae5b3e4721654.

In this case I'm not sure about the best way to fix it. Feel free to use
a different approach if preferred (for example calling
swapchain_frontbuffer_updated from context_unmap_bo_address).
