It depends.

Are zombies toxic to wolves?

If yes, I would expect their sense of smell plus intelligence would lead them to avoid them quite easily.

If no, then the wolves would be a bigger threat to Z’s. That is if they even bother with them.

The other thought. Why would the wolves be interested in zombies as food? If the majority of humans are gone, then so is human civilization’s impact on the biosphere.

Within a year or so, the wolves would have so much extra natural food that the Zs would just be avoided.
