[PATCH v4 2/7] memory: Do not refer to "memory region's reference count"

[Akihiko Odaki]

Now MemoryRegions do have their own reference counts, but they will not
be used when their owners are not themselves. However, the documentation
of memory_region_ref() says it adds "1 to a memory region's reference
count", which is confusing. Avoid referring to "memory region's
reference count" and just say: "Add a reference to a memory region".
Make a similar change to memory_region_unref() too.
