Subject: [net-next 01/14] net/mlx5e: Remove non-essential TLS SQ state bit

From: Tariq Toukan <tariqt@...dia.com>

Maintaining an SQ state bit to indicate TLS support
has no real need, a simple and fast test [1] for the SKB is
almost equally good.

[1] !skb->sk || !tls_is_sk_tx_device_offloaded(skb->sk)
