[bluetooth-next 02/15] Bluetooth: Start SMP procedure

[Vinicius Costa Gomes <vinicius.gomes@openbossa.org>]

From: Anderson Briglia <anderson.briglia@openbossa.org>

Start SMP procedure for LE connections. This modification intercepts
l2cap received frames and call proper SMP functions to start the SMP
procedure. By now, no keys are being used.
