If the ancestor device modifier is used and the value of the device clause is evaluated to 1, the ancestor device shall be used for the execution. Since the reverse offloading is not supported yet, the target construct execution is always initiated from the host, not from the device. So, if the ancestor modifier is specified, just execute target region on the host.
