Disable CLOD (Lod constant) state emit. The values emitted were
possibly negative, hence clobbering the leading register-id byte.
Fixed the calculation of the values to prevent negative numbers being
emitted, but the code still doesn't implement texture LOD bias
correctly, so leave it disabled overall.
