wined3d: Set swapchain container before flagging front buffer with SFLAG_INDRAWABLE

[Allan Tong]

This fixes a regression caused by commit
bf50e07f342a5d26ed1ceb600e9a9a989d58ba97 where the d3d visual tests
failed the sanity check and skipped the rest of the tests with
ORM_FBO.  ModifyLocation thought the front buffer was an offscreen
surface and was flagging it with SFLAG_INTEXTURE.
