qom/object.c provides object_property_get_TYPE() and
object_property_set_TYPE() for a number of common types. These are
all convenience wrappers around object_property_get_qobject() and
object_property_set_qobject().
Except for object_property_get_uint16List(), which is unusual in two ways:
* It bypasses object_property_get_qobject(). Fixable; the previous
commit did it for object_property_get_enum())
* It stores the value through a parameter. Its contract claims it
returns the value, like the other functions do. Also fixable.
Fixing is not worthwhile, though: object_property_get_uint16List() has
seen exactly one user in six years.
Convert the lone user to do its job with the generic
object_property_get_qobject(), and drop object_property_get_uint16List().
