s390/pci: Fix dev.dma_range_map missing sentinel element
The fixed commit sets up dev.dma_range_map but missed that this is
supposed to be an array of struct bus_dma_region with a sentinel element
with the size field set to 0 at the end. This would lead to overruns in
e.g. dma_range_map_min(). It could also result in wrong translations
instead of DMA_MAPPING_ERROR in translate_phys_to_dma() if the paddr
were to not fit in the aperture. Fix this by using the
dma_direct_set_offset() helper which creates a sentinel for us.
