Subject: [PATCH mlx5-next 2/5] net/mlx5: Reliably return TLS device capabilities

From: Leon Romanovsky <leonro@...dia.com>

The capabilities returned from the FW are independent to the compiled
kernel and traditionally rely on the relevant CAPs bit only.

The mlx5_accel_is_ktls_*() functions are compiled out if CONFIG_MLX5_TLS
is not set, which "hides" from the user the information that TLS can be
enabled on this device.
