d3d11: Fix crash when srv is submitted to ClearUnorderedAccessViewUintHEADmaster

* The Settlers submits (possibly incorrectly) an SRV to ClearUnorderedAccessViewUint. The static_cast in the function does not translate correctly and crashes.

Native D3D11 behavior is to ignore the bad parameter entirely. It does not clear the SRV nor does it fault or even error with the DEBUG validator.
