    Bluetooth: hci_sync: Using hci_cmd_sync_submit when removing Adv Monitor
    
    [ Upstream commit 88cd6e6b2d327faa13e4505b07f1e380e51b21ff ]
    
    Since the d883a4669a1de be introduced in v6.4, bluetooth daemon
    got the following failed message of MGMT_OP_REMOVE_ADV_MONITOR
    command when controller is power-off:
    
    bluetoothd[20976]:
    src/adapter.c:reset_adv_monitors_complete() Failed to reset Adv
    Monitors: Failed>
    
    Normally this situation is happened when the bluetoothd deamon
    be started manually after system booting. 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().
    
    Fixes: d883a4669a1de ("Bluetooth: hci_sync: Only allow hci_cmd_sync_queue if running")
