wined3d: Handle context acquisition failure in wined3d_device_create_primary_opengl_context_cs().

Now that we no longer always call context_acquire() from
swapchain_init(), context acquisition can fail here instead.
This fixes a regression introduced by commit
64d41b3dec0635c56268be64d407ed9bfd8c0695.
