From: Johan Hedberg <johan.hedberg@xxxxxxxxx> When a new hci_conn object the remote SSP authentication requirement is set to the invalid value 0xff to indicate that it is unknown. Once pairing completes however the code was leaving it as-is. In case a new pairing happens over the same connection it is important that we reset the value back to unknown so that the pairing code doesn't make false assumptions about the requirements.
