tu: Fix FragCoord offset when HW viewport offset is enabled

Browse source 
FragCoord seems to have the offset applied to it, so we don't need to
subtract it out. Fixes upcoming test
dEQP-VK.renderpasses.dynamic_rendering.primary_cmd_buff.custom_resolve.monolithic.fdm_nonsubsampled_multiview_with_offset.

Fixes: b34b089ca1 ("tu: Use GRAS bin offset registers")
