Which means that bluetoothd received MGMT_EV_INDEX_ADDED event after kernel runs hci_power_off(). Base on doc/mgmt-api.txt, the MGMT_OP_REMOVE_ADV_MONITOR command can be used when the controller is not powered. This patch changes the code in remove_adv_monitor() to use hci_cmd_sync_submit() instead of hci_cmd_sync_queue().
