[dpdk-dev] [PATCH] vfio: change default per vfio_cfg map all dpdk segments for DMA

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

As all vfio_cfgs need to map all dpdk segments for DMA, but now only
default_vfio_cfg map it. This patch changes rte_vfio_setup_device()
as a default map, so that IOMMU progrming does notneed to map dpdk
segments separately.
