factorysetup: don't skip BLE if already flashed

If the BLE boot check failed further below, repeating the factory
setup made it report success, as _verify_ble() only checks if the BLE
firmware was flashed properly already, and the boot check is skipped
in that case.

For now we simply remove this check so every attempt tries the whole
BLE setup & verification procedure. To be refactored later.
