Mackie Protocol: Show dB values for Mixbus "Send" levels.

No sense rewriting it now, but the correct way to approach
   this stuff is to pass in the control, and use
   the appropriate one of: interface, internal, or user values.
   in this case, get_user would have returned dB for both Ardour and Mixbus sends.
