Linas Vepstas 650f7b3b2f [POWERPC] pseries: Handle null iommu dma-window property correctly 
Some versions of pSeries firmware fail to set up a
dma-window property for PCI slots that are unoccupied.
As a result, the loop searching for this propery, in
pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting
in a NULL pointer dereference later in the routine. This
patch prevents the crash, and prints a warning message.

This is theoretically a rare error, as it occurs on what
is hopefully just beta levels of firmware. But just in case
this firmware escapes into the wild, this patch will avoid
the crash.
