[dpdk-stable] [dpdk-dev] [PATCH v2 RESEND] vfio: fix resource leak when mapping fails

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

Currently, only the 'vfio_dev_fd' is closed in failure path, so
some resources are not released(such as 'vfio_group_fd'). The
rte_vfio_release_device() should be used to avoid this problem.

Fixes: 33604c31354a ("vfio: refactor PCI BAR mapping")
