[PULL 10/21] qom: Improve error message displayed with missing object properties

[Eduardo Habkost]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Instead of only displaying the property missing, also display
the object name. This help developer to quickly figure out the
mistake without opening a debugger.
