Calling bt_conn_set_auto_conn one can decide if auto connect shall
be used. If so, everytime the connection is lost, passive scanning
will be enabled to listen for connectable advertisements from
remote device and re-establish the connection.
Auto connect can be disabled if one decide to disconnect from
this device using bt_disconnect or call bt_conn_set_auto_conn
with auto_conn flag set to false.

There's no need to check for BT_CONN_CONNECTED for these HCI events or
ACL data. Even if the connection is being disconnected the stack will
do the right thing when the disconnect_complete event occurs.
Furthermore, these branches were actually leaking the bt_conn if the
state wasn't connected after being looked up.
