bugfix: manually trigger cvTimer on cv change

[csboling]

What does this PR do?

Changes what appears to be a typo manually triggering adcTimer instead of cvTimer in tele_cv, which was causing DACs not to update until the CV timer expires when using CV ops.

How should this be manually tested?

Report from testing with an oscilloscope on Lines: "CV state changes have c. 200us of latency + c. 500us of jitter after this update" (down from as much as 6ms)

Any background context you want to provide?
