[PATCH 6.6 082/261] octeontx2-pf: Set correct sequence for carrier off and tx queue stop

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Suman Ghosh <[email protected]>

[ Upstream commit 16809472409d998afcda402e32b8229b389337c4 ]

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.
