gallium/st: correct range for int16 

This fixes the following dEQP tests:

- dEQP-GLES3.functional.shaders.operator.unary_operator.minus.lowp_uvec2_fragment
- dEQP-GLES3.functional.shaders.operator.unary_operator.minus.lowp_uvec4_fragment
- dEQP-GLES3.functional.shaders.operator.unary_operator.minus.mediump_uvec2_fragment
- dEQP-GLES3.functional.shaders.operator.unary_operator.minus.mediump_uvec4_fragment
