wifi/olpc-mesh: fix the stage2
There's multiple things wrong there, but unnoticed because the error handling
was entirely missing or nobody is using thie anymore.
The Mesh ID needs to be set while the device is down. Also, the channel
needs to be set last, because that's what triggers the connection
attempt. For that the device needs to be up.
Also, fix the error handling.
