[D3D] Fix graphical corruption in DungeonSiege

[Lionel Ulmer]

This fixes the most glaring corruptions when DungeonSiege abruptly decides
at the middle of one level to activate multi-texturing.

            Lionel

Changelog:
 - fix graphical corruption on surface lock when multi-texturing
   is active
