[PATCH 2/3] net/mlx5: fix build with MinGW 13

[Thomas Monjalon]

After an upgrade to MinGW version 13, compilation breaks:

drivers/net/mlx5/windows/mlx5_ethdev_os.c:285:69: error:
	'dev_link.<U1000>.<Uaf00>.link_autoneg' may be used uninitialized

This is because link_autoneg is never set in mlx5_link_update().
It can be set to the previous value (no change).
Also it does not make sense to check this value to return the update status
as it does not change.

Fixes: 6fbd73709ee4 ("net/mlx5: support link update on Windows")
