Bluetooth: hci_conn: Fix not restoring ISO buffer count on disconnect
When disconnecting an ISO link the controller may not generate
HCI_EV_NUM_COMP_PKTS for unacked packets which needs to be restored in
hci_conn_del otherwise the host would assume they are still in use and
would not be able to use all the buffers available.
