net/mlx5e: Set local Xoff after FW update
[ Upstream commit aca0c31af61e0d5cf1675a0cbd29460b95ae693c ]
The local Xoff value is being set before the firmware (FW) update.
In case of a failure where the FW is not updated with the new value,
there is no fallback to the previous value.
Update the local Xoff value after the FW has been successfully set.
