Dariusz Stojaczyk db9d32b8b7 vfio: check if group fd is already open

Always attempt to find already opened fd for an iommu
group as subsequent attempts to open it will fail.

There's no public API to check if a group was already
bound and has a container, so rte_vfio_container_group_bind()
shouldn't fail in such case.
