[PATCH v1 2/2] memory: Update description of memory_region_is_mapped()

[David Hildenbrand <david@redhat.com>]

memory_region_is_mapped() only indicates if the memory region is mapped
into a different memory region, and only if it is mapped directly
(->container), not via an alias.

Update the documentation to make this clearer.
