present: Check tiling info for flips
The kernel driver doesn't handle flipping between buffers with different tiling parameters correctly. Fixes display corruption with fullscreen apps using different tiling modes (e.g. due to R600_DEBUG=notiling or R600_DEBUG=no2d) via DRI3. Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
