    D3D11: Fix dirty current value updates.

    Fixes a bug where subsequent updates to a "current value" (disabled)
    Vertex Attribute would not trigger the state change to D3D11 such that
    the updated buffer handle would be applied to D3D11. Also adds a test
    to cover the problem case.

    This bug was introduced in 2bc947334cad:
    "D3D11: Minor optimizations to vertex attribute application."
