bus/pci: fix leak on VFIO mapping error

Browse Source 
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: 33604c3135 ("vfio: refactor PCI BAR mapping")
