Surfaces are created with SFLAG_INSYSMEM(see dlls wined3d/surface.c, surface_private_setup), but due to the SFLAG_DS_ONSCREEN and SFLAG_DS_OFFSCREEN flags as well as your newly created SFLAG_DS_SYSMEM this doesn't apply for depth stencils. This problem should go away once depth stencils use the normal location flags.
