3.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hedberg <johan.hedberg@xxxxxxxxx>
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.
