Unlike the old allocator, alloc_iova_fast() will return 0 if it failed
to allocate a PFN. Since the callers of dma_ops_alloc_iova() would end
up treating that as a valid address, translate it to the DMA_ERROR_CODE
that they would expect.

Or you can compute how many 512G-covering, i.e., PGD entries

arch_teardown_dma_ops() being the inverse of arch_setup_dma_ops()
,dma_ops should be cleared in the teardown path. Currently, only the
device's iommu mapping structures are cleared in arch_teardown_dma_ops,
but not the dma_ops. So on the next reprobe, dma_ops left in place is
stale from the first I
