net/mlx5e: Require mlx5 tc classifier action support for IPsec prio capability

Browse Source 
[ Upstream commit 06827e27fdcd197557be72b2229dbd362303794f ]

Require mlx5 classifier action support when creating IPSec chains in
offload path. MLX5_IPSEC_CAP_PRIO should only be set if CONFIG_MLX5_CLS_ACT
is enabled. If CONFIG_MLX5_CLS_ACT=n and MLX5_IPSEC_CAP_PRIO is set,
configuring IPsec offload will fail due to the mlxx5 ipsec chain rules
failing to be created due to lack of classifier action support.
