Message printing issue with brake disengage

[d-loret]

I think we should remove the print statements when the servo is actually enabled and we don't wait for the brake to disengage (e.g. here). Strictly speaking, it brakes the real-time guarantee. In practice, it makes it difficult to look at Fastcat's output when the profile commands are used periodically, such as in EELS.
