wined3d: When restoring pixel format in context_release(), mark the context as needing to be set on the next context_acquire().

If we had to restore the pixel format then we know it won't be what we need
when the app calls into wined3d again.  This helps avoid the GetPixelFormat()
in context_acquire().
