vfio_noiommu_attach_group has two callers: 1) __vfio_container_attach_groups is called by vfio_ioctl_set_iommu, which just called vfio_iommu_driver_allowed 2) vfio_group_set_container requires already checks ->noiommu on the vfio_group, which is propagated from the iommudata in vfio_create_group so this check is entirely superflous and can be removed.
