Rename obj->tiling_changed to obj->fence_dirty so that it is clear that it flags when the parameters for an active fence (including the no-fence) register are changed. Also, do not set this flag when the object does not have a fence register allocated currently and the gpu does not depend upon the unfence. This case works exactly like when a tiled object lost its fence and hence does not need additional handling for the tiling change in the code. v2: Use fence_dirty to better express what the flag tracks and add a few more details to the comments to serve as a reminder of how the GPU also uses the unfenced register slot.
