memory: add getter for owner
Whenever memory regions are accessed outside the BQL, they need to be
preserved against hot-unplug. MemoryRegions actually do not have their
own reference count; they piggyback on a QOM object, their "owner".
The owner is set at creation time, and there is a function to retrieve
the owner.
