Revert "Remove FL 11.0 restriction for D3D11VA"

Browse source 
Even with a fix for the Intel IVB rendering issue, there are still problems on
other older cards that make it not really worth it to enable D3D11VA.

The big benefit of D3D11VA is independent flip in windowed mode using
overlays and that isn't supported on those old cards anyway.

This reverts commit 7074463d0f.
