Andrew Tridgell 996b36531b AP_DroneCAN: force DroneCAN zero throttle when disarmed
if a user has set CAN_D1_UC_ESC_RV which is the mask of ESCs that are
reversible we were sending -8191 when disarmed, which is full reverse
throttle. This is the correct output when armed as it is treated as
full reverse at "PWM" 1000 and stopped at 1500, but when disarmed we
should always send zero or the user may find all ESCs spin up at full
reverse when disarmed if the ESC supports reverse throttle (which is
rare in DroneCAN ESCs)
