AI_EnsureCorrectMode: Don't select the amplifier when changing the clamp mode

The function does accept a selectAmp parameter already and also selects
the amplifier if requested. So when we set the clamp mode in the end we
either have selected the amplifier already or don't want to select it. So
in both cases we don't have to select it again.
