wined3d: Restore the fragment replacement prog after depth_blt.

The current code properly enabled/disabled GL_ARB_fragment_program
after a depth blit, but it did not restore the bound fragment program
properly. This leads to problems if a depth blit was done between two
draws without any change of the fragment processing settings.
