thunderbolt: Allow clearing the key
If secure authentication of a devices fails, either because the device already has another key uploaded, or there is some other error sending challenge to the device, and the user only wants to approve the device just once (without a new key being uploaded to the device) the current implementation does not allow this because the key cannot be cleared once set even if we allow it to be changed. Make this scenario possible and allow clearing the key by writing empty string to the key sysfs file.
