I don't think is is correct. There are two possible domains for address
types: the user space-facing interface that has three values: BR/EDR, LE
public & LE random, and the internal one which maps to HCI that has two
values: random or public. You'd need to convert from the former to the
latter when making the lookup call, i.e:

	conn = hci_conn_hash_lookup_le(hdev, &cp->addr.bdaddr,
				       le_addr_type(cp->addr.type));
