Bluetooth: hci_core: Cancel request on command timeout
If command has timed out call __hci_cmd_sync_cancel to notify the hci_req since it will inevitably cause a timeout. This also rework the code around __hci_cmd_sync_cancel since it was wrongly assuming it needs to cancel timer as well, but sometimes the timers have not been started or in fact they already had timed out in which case they don't need to be cancel yet again.
