Make FEDisplacementMap a pass-through filters if the origin is tainted.

The regression is that FEDisplacementMap is now a pass-through for tainted input.
It doesn't look like there is actually a cross-origin image, but instead that other filters
earlier in the chain taint the input.

This is working as intended.
