net/mlx5: Add vhca_id_type support to IPsec alias creation

Browse source

When creating an alias FT for MPV IPsec, if alias creation with
sw_vhca_id is supported use it instead of using the hw_vhca_id.

This in turn allows IPsec to work properly after live migration,
in case a VF was live migrated and his hw_vhca_id changed due to
migration which can happen if you migrate to a VF with a different index
than yours, IPsec would fail to start post migration, this patch
resolves the issue by using sw_vhca_id instead which doesn't change post
migration.
