Subject: [ 176/218] Bluetooth: Fix sending a HCI Authorization Request over LE links

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vinicius Costa Gomes <vinicius.gomes@...nbossa.org>

commit d8343f125710fb596f7a88cd756679f14f4e77b9 upstream.

In the case that the link is already in the connected state and a
Pairing request arrives from the mgmt interface, hci_conn_security()
would be called but it was not considering LE links.
