net/mlx5: HWS, Enable IPSec hardware offload in legacy mode

IPSec hardware offload in legacy mode should not be affected by the
steering mode, hence it should also work properly with hmfs mode.

Remove steering mode validation when calculating the cap for packet
offload, this will also enable the missing cap MLX5_IPSEC_CAP_PRIO
needed for crypto offload.
