CWD is a prion, so it has the potential for inter-species spread. Unfortunately, there's likely no guarantee wolves would help this issue. Additionally, infectious materials shed by animals remain in the environment for long periods of time.
It has the potential, but there's no evidence yet of it spreading to canines. Or really any animals other than deer/sheep for this particular outbreak. Fewer deer would mean fewer hosts to spread the prions. Wolves would also be able to kill infected deer earlier before they've hit their maximum prion load.
