When alloc default domain for an iommu_group in
probe_alloc_default_domain, the expected domain type
of each device in the iommu_group is checked in a loop,
if two devices require different types, the loop can
be broken since the default domain will be set to
iommu_def_domain_type.
Return 1 when this happened to break the loop in
__iommu_group_for_each_dev.
