[ 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().
