A2MP doesn't use part of the L2CAP chan ops API so we just create general
empty function instead of the A2MP specific one.Signed-off-by: Gustavo Padovan

Make A2MP channel special channel which do not reference hci_conn.
This prevents from keeping ACL connection open when all L2CAP
channels got closed.hci_conn_hold and hci_conn_put are not reference counts on the
hci_conn structure in the typical way. They are reference counts for
the ACL. When you do the last hci_conn_put, the ACL is disconnected
after a timeout.Reported-by: Mat Martineau
