Fix order of parameters to stop_touch() in Mackie::Control

Fix order of parameters to stop_touch() in Mackie::Control

Reverse the parameters of Mackie::Control::stop_touch() to make them
consistent with AutomationControl::stop_touch(), and fix up the call to
AutomationControl::stop_touch() to have the parameters in the correct
order.

Unfortunately, I don't possess any devices that speak the Mackie protocol, so
though the patch seems logical and correct to me, I have no way of testing it.
If anyone has a device with touch faders that speaks Mackie, I'd be glad of any
confirmation that it at least doesn't break anything.
