From: Aya Levin <ayal@xxxxxxxxxxxx> [ 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.
