powerpc/pci: Fix unmapping of IO space on 64-bit
A typo/thinko made us pass the wrong argument to __flush_hash_table_range
when unplugging bridges, thus not flushing all the translations for
the IO space on unplug. The third parameter to __flush_hash_table_range
is `end', not `size'.
This causes the hypervisor to refuse unplugging slots.
