qom: Change object_get_canonical_path_component() not to malloc
object_get_canonical_path_component() returns a malloced copy of a property name on success, null on failure. 19 of its 25 callers immediately free the returned copy. Change object_get_canonical_path_component() to return the property name directly. Since modifying the name would be wrong, adjust the return type to const char *. Drop the free from the 19 callers become simpler, add the g_strdup() to the other six.
