[RFCv2 4/4] Bluetooth: check adv_entries in hci_connect() for LE devices

[anderson.briglia@openbossa.org]

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

In case we are connecting to a LE device, we need to check the adv_entries
in order to know the bdaddr_type of that device.
Additionally, hci_le_connect() was changed to handle the bdaddr_type
info.
