net/mlx5e: Update TX ESN context for IPSec hardware offload

ESN context must be synced between software and hardware for both RX
and TX. As the call to xfrm_dev_state_advance_esn() is added for TX,
this patch add the missing logic for TX. So the update is also checked
on every packet sent, to see if need to trigger ESN update worker.
