commander: fix broken 'commander arm/disarm' CLI

Regression from #13613.

VEHICLE_CMD_COMPONENT_ARM_DISARM from CLI would enter the
ARMING_STATE_IN_AIR_RESTORE logic. This was never intended for disarming
(and leads to state machine transition failures), and IMO it is also not
intended for commands from CLI.
