Deleted code specific to fixed wing that set motors to mincommand when

disarmed.

Ensure that servo mixes that use calculated throttle output (motor 0)
adhere to the armed/disarmed state, this is achieved by ensuring that
motor outputs, including the effects of MOTOR_STOP are calculated BEFORE
using motor 0 as an input source for the servo mixer.
