From: Leon Romanovsky <leonro@xxxxxxxxxx>
The mlx5e_macsec_cleanup() routine has pointer dereferencing if mlx5 device
doesn't support MACsec (priv->macsec will be NULL) together with useless
comment line, assignment and extra blank lines.
Fix everything in one patch.
Fixes: 1f53da676439 ("net/mlx5e: Create advanced steering operation (ASO) object for MACsec")
