Fix a typo in the ppce500_pci vmstate definition which meant that
we were migrating the struct pci_inbound using the vmstate for
pci_outbound. Fortunately the two structures have exactly the same
format at the moment (four uint32_ts) so this was harmless, and
we can correcting the typo without a migration compatibility
break because the vmstate name doesn't go out on the wire.

Big fat disclaimer: I believe the remark about this not
being a compat break to be true, but I haven't tested it!
