octeontx2-pf: Set correct sequence for carrier off and tx queue stop

During link down event, we were doing netif_tx_stop_all_queues() first
and then netif_carrier_off(). This can cause a potential race since
carrier is still on during down event. This patch reverse the calling
order to fix the issue.
