intel/isl: Set null surface format to R32_UINT
It appears we never had a test in piglit or deqp sampling from a null
surface...
It turns out this triggers a hang on IVB only. Updating the null
surface format to R32_UINT fixes the hang on ivb and doesn't affect
other platforms, so set it by default for all platforms.
