[PATCH v3 6/8] net/mlx5: store modify field action

[Dariusz Sosnowski <dsosnowski@nvidia.com>]

When template table is created, list of unmasked actions is recorded for
future flow rule insertions.
This patch expands entries for RTE_FLOW_ACTION_TYPE_MODIFY_FIELD actions
in this list with a copy of the action from the template.
This will be used in follow up commits which add flow rule operation
validation. Specifically, to validate that
RTE_FLOW_ACTION_TYPE_MODIFY_FIELD action passed by the user is correctly
configured.
