ddraw: Improve IDirect3DDevice7_Load implementation.

Copies palette and colorkey earlier in the helper function, before
copying image, also skips UpdateSurface when palette is missing. This
prevents unnecessary surface (re)loads in wined3d, and gets rid of
some wined3d palette error messages in Sacrifice.
