The INFO-level logging guard in _status_changed() called device.ping()
before logging, purely to show accurate online status. But ping() has
side effects — it sets device.online based on the result. When a
ConnectionStateChangedEvent correctly marked a device online, the
subsequent _status_changed() callback would re-ping. If the device
wasn't ready yet (e.g. Centurion headset still booting), the ping
timed out and set online back to False, requiring 2-3 power cycles
to sync state.
Remove the unnecessary ping — the log message already reads
device.online which reflects the state set by the event handler.
