opae_adapter_free() function is use to free the adapter data struct. But in rawdev framework,
the rte_rawdev_pmd_release() will release this adapter because the adapter will pointer to rawdev->dev_private when
we create the rawdev in ifpga_rawdev_create() . And in rte_rawdev_pmd_release(), it will free the rawdev->dev_private.
