Subject: [PATCH 083/104] Bluetooth: Fix encryption key size for peripheral role

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

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

From: Andre Guedes <andre.guedes@...nbossa.org>

commit 89cbb4da0abee2f39d75f67f9fd57f7410c8b65c upstream.

This patch fixes the connection encryption key size information when
the host is playing the peripheral role. We should set conn->enc_key_
size in hci_le_ltk_request_evt, otherwise it is left uninitialized.
