At device probe, the fslmc bus driver calls rte_vfio_get_group_fd() to
get a fd associated to a vfio group. This function first checks if the
group is already opened, else it opens /dev/vfio/%u, and increases the
number of active groups in default_vfio_cfg (which references the
default vfio container).
When adding the first group to a vfio_cfg, the caller is supposed to
pick an IOMMU type and set up DMA mappings for container, as it's done
by pci bus, but it is not done here. Instead, a new container is created
and used.
This prevents the pci bus driver, which uses the default_vfio_cfg
container, to configure the container because
default_vfio_cfg->active_group > 1.
This patch fixes the issue by always creating a new container (and its
associated vfio_cfg) and binding the group to it.
