->Fixed incorrect scaling betwen PWM values and Volz protocol values
->In the scaling formula are hardcoded PWM values min=1000 and max=2000. The idea behind this is to be able to change Volz range, when you use SERVOn_MIN and SERVOn_MAX parameters.

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach
