These commands don't require the adapter to be up and running so don't
use hci_cmd_sync_queue which would check that flag, instead use
hci_cmd_sync_submit which would ensure mgmt_class_complete is set
properly regardless if any command was actually run or not.

Fixes: d883a4669a1d ("Bluetooth: hci_sync: Only allow hci_cmd_sync_queue if running")
