s390x/pci: fixup the code walking IOMMU tables
Current s390x PCI IOMMU code is lack of flags' checking, including:
1) protection bit
2) table length
3) table offset
4) intermediate tables' invalid bit
5) format control bit
This patch introduces a new struct named S390IOTLBEntry, and makes up
these missed checkings. At the same time, inform the guest with the
corresponding error number when the check fails. Finally, in order to
get the error number, we export s390_guest_io_table_walk().
