Reboot and auto reconnect will loading for a long time when APM set CAN_P1_DRIVER to 1

[cuav-chen2]

Issue details

In current Ardupilot master branch if compile with copter, when set CAN_P1_DRIVER or CAN_P2_DRIVER to 1 and send a reboot command to autopilot, Mission Planner will reconnect automaticlly and enter a infinite loading state just like that:

In order to exit this loading state, you must disconnect and reconnect manually in MP, or click the Retry Now button in CONFIG tabs. When MP staying in the loading state, the console window shows that it reading a 'None' param. This issue will not occur if APM changes GPS1_TYPE to any value. But if reset all paramters to default, this issue will reappear.

I guess it might be a MP issue, see ArduPilot/ardupilot#27608.
