CVE-2024-35959: linux kernel — Fix

Description

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix mlx5e_priv_init() cleanup flow When mlx5e_priv_init() fails, the cleanup flow calls mlx5e_selq_cleanup which calls mlx5e_selq_apply() that assures that the `priv->state_lock` is held using lockdep_is_held(). Acquire the state_lock in mlx5e_selq_cleanup().
