Bluetooth: Update background scanning from hci_conn_params_clear
Bluetooth: Update background scanning from hci_conn_params_clear

When calling hci_conn_params_clear function, it should update the

update it.

For the case when the function is used during unregister of a
controller, an extra safe guard is but in place.
