Remove spurious WTF on pre-U devices.

aosp/2162425 added a WTF if a NetworkAgent changed state before
its native network has been created. This was intended to apply
only to the new U+ codepath, where networks are always created
immediately as soon as their agents register them. But the WTF is
logged on pre-U devices as well.

Fix this so that the WTF is only logged when the new codepath is
running.
