Bluetooth: hci_sync: Remove unused hci_cmd_sync_dequeue_once()

Browse Source 
hci_cmd_sync_dequeue_once() had a single in-tree caller,
hci_cancel_connect_sync(), which now holds cmd_sync_work_lock across the
in-flight create flag test and the dequeue and so open-codes the lookup
and cancel under that lock. That leaves the exported
hci_cmd_sync_dequeue_once() with no in-tree user, so remove it along with
its declaration.
