Bluetooth: Fix setting correct authentication information for SMP STK
commit fff3490f47810e2d34b91fb9e31103e923b11c2f upstream.
When we store the STK in slave role we should set the correct
authentication information for it. If the pairing is producing a HIGH
security level the STK is considered authenticated, and otherwise it's
considered unauthenticated. This patch fixes the value passed to the
hci_add_ltk() function when adding the STK on the slave side.
