[ 059/108] Bluetooth: Change signature of smp_conn_security()

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

commit cc110922da7e902b62d18641a370fec01a9fa794 upstream.

To make it clear that it may be called from contexts that may not have
any knowledge of L2CAP, we change the connection parameter, to receive
a hci_conn.

This also makes it clear that it is checking the security of the link.
