    net/mlx5: Fix missing devlink lock in SRIOV enable error path

    The cited commit miss to add locking in the error path of
    mlx5_sriov_enable(). When pci_enable_sriov() fails,
    mlx5_device_disable_sriov() is called to clean up. This cleanup function
    now expects to be called with the devlink instance lock held.

    Add the missing devl_lock(devlink) and devl_unlock(devlink)

    Fixes: 84a433a40d0e ("net/mlx5: Lock mlx5 devlink reload callbacks")
