net/mlx5e: Prepare IPsec packet offload for switchdev mode

As the uplink representor is created only in switchdev mode, add a local
variable for IPsec to indicate the device is in this mode.
In this mode, IPsec ROCE is disabled, and crypto offload is kept
as it is. However, as the tables for packet offload are created in FDB,
ipsec->rx_esw and ipsec->tx_esw are added.
