Bluetooth: hci_sync: Using hci_cmd_sync_submit when removing Adv Monitor 

Since the d883a4669a 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: d883a4669a ("Bluetooth: hci_sync: Only allow hci_cmd_sync_queue if running")
