drm/i915/ttm: fix sg_table construction
If we encounter some monster sized local-memory page that exceeds the
maximum sg length (UINT32_MAX), ensure that don't end up with some
misaligned address in the entry that follows, leading to fireworks
later. Also ensure we have some coverage of this in the selftests.
v2(Chris):
- Use round_down consistently to avoid udiv errors
v3(Nirmoy):
- Also update the max_segment in the selftest
