net/mlx5e: Fix possible race condition in macsec extended packet number update routine

Browse source

Currenty extended packet number (EPN) update routine is accessing
macsec object without holding the general macsec lock hence facing
a possible race condition when an EPN update occurs while updating
or deleting the SA.
Fix by holding the general macsec lock before accessing the object.
