[Bug] Fixed-wing detected landing but did not disarm

[anaam-wingxpand]

Describe the bug

Landing was detected but did not disarm, despite COM_DISARM_LAND = 2 seconds. In fact, 5 seconds later the motor started again as takeoff was detected, even though it wasn't actually taking off.

To Reproduce

1. The operator shook the drone to pre-trigger launch.
2. The operator held onto the drone. 2 seconds later, the motor stopped as landing was detected
3. The operator went to go set the drone down, and 5 seconds later the motors started again as takeoff was detected
4. The operator disarmed the drone via QGroundControl

Expected behavior

The drone should've disarmed 2 seconds after landing, since COM_DISARM_LAND = 2 seconds. The motors should never started up again on their own.
