[ Upstream commit 5cd39b6e9a420329a9a408894be7ba8aa7dd755e ]
On failure to attach the netdev, fix the rollback by re-setting the
device's state back to MLX5E_STATE_DESTROYING.
Failing to attach doesn't stop statistics polling via .ndo_get_stats64.
In this case, although the device is not attached, it falsely continues
to query the firmware for counters. Setting the device's state back to
MLX5E_STATE_DESTROYING prevents the firmware counters query.
Fixes: 26e59d8077a3 ("net/mlx5e: Implement mlx5e interface attach/detach callbacks")
