The block in pci_dma_dev_setup_pSeriesLP for dma_window == NULL can be
removed because we will only teminate the loop if we had already allocated
a iommu table for that node or we found a window.  While there may be
no window for the device, the intresting part is if we are reusing a
table or creating it for the first device under it.
