Get the return value returned by the most recent API function call.
Functions return zero to indicate success, and non-zero to indicate an error.
Warning
DO NOT call of_getreturnedvalue after calling of_cleanup.
This function sets the pointer for _objs to NULL,
which would be dereferenced by of_cleanup.
