iommufd: Avoid duplicated __iommu_group_set_core_domain() call
For the fault-capable hwpts, the iommufd_hwpt_detach_device() calls both iommufd_fault_domain_detach_dev() and iommu_detach_group(). This would have duplicated __iommu_group_set_core_domain() call since both functions call it in the end. This looks no harm as the __iommu_group_set_core_domain() returns if the new domain equals to the existing one. But it makes sense to avoid such duplicated calls in caller side.
