iommu: Require passing new handles to APIs supporting handle
Add kdoc to highligt the caller of iommu_[attach|replace]_group_handle()
and iommu_attach_device_pasid() should always provide a new handle. This
can avoid race with lockless reference to the handle. e.g. the
find_fault_handler() and iommu_report_device_fault() in the PRI path.
