Subject: [net-next 09/12] net/mlx5e: Fix mlx5e_tx_reporter_create return value

From: Aya Levin <ayal@...lanox.com>

Return error when failing to create a reporter in devlink. Since
NET_DEVLINK mandatory to MLX5_CORE in Kconfig, returned pointer
can't be NULL and can only hold an error in bad path.
