isl: Don't use surface format R32_FLOAT for typed atomic integer operations
From Skylake PRM Surface Formats section: "The surface format for the typed atomic integer operations must be R32_UINT or R32_SINT." Fixes an error and a piglit GPU hang in simulation environment. Piglit test: gl45-imageAtomicExchange-float.shader_test Suggested-by: Francisco Jerez <[email protected]> Signed-off-by: Anuj Phogat <[email protected] Reviewed-by: Kenneth Graunke <[email protected]> Cc: "18.0 17.3" <[email protected]>
