D3D: Fixed D3D validation error during EFB to texture copy

Browse Source 
Texture was being bound as a render target while still being set as a shader resource.
D3D automatically unbinds the SRV in this case and generates a validation error.
The fix is to manually unbind SRV, render into it and then re-bind to old slots.
