s390x/pci: fix failures of dma map/unmap
In commit d78c19b5cf4821d0c198f4132a085bdbf19dda4c, vfio code stores
the IOMMU's offset_within_address_space and adjusts the IOVA before
calling vfio_dma_map/vfio_dma_unmap. But s390_translate_iommu already
considers the base address of an IOMMU memory region.
Thus we use pal as the size and 0x0 as the base address to initialize
IOMMU memory subregion.
