InputWizard: cancel out when board is disconnected

If a user plugs in a board and then unplugs it during the middle
of calibration their original settings (including arming) will be
restored.  However, if they then start moving the sticks to test
the range they will end up arming the system which is dangerous
(although props should have been removed to do this step).

Telemetry scheduler config fix
[STABILIZATION]: 1) Enhanced coordinated flight to include a yaw damper when
flying straight.
2) Added separate field for coordinated flight control gains.
[Coordinated Flight]: Removed bound from coordinated flight. Now the
vehicle will attempt to return to its original heading even in strong
winds.
