Alex Bennée 2f3a57ee47 cputlb: ensure we save the IOTLB data in case of reset
Any write to a device might cause a re-arrangement of memory
triggering a TLB flush and potential re-size of the TLB invalidating
previous entries. This would cause users of qemu_plugin_get_hwaddr()
to see the warning:

  invalid use of qemu_plugin_get_hwaddr

because of the failed tlb_lookup which should always succeed. To
prevent this we save the IOTLB data in case it is later needed by a
plugin doing a lookup.
