Revert of Remove references between RTCPeerConnection and RTCDataChannel. (patchset #3 id:40001 of https://codereview.chromium.org/1634073003/ )

Reason for revert:
It turns out that the underlying WebRTC DataChannel  objects does not maintain a reference to the WebRTC PeerConnection, so we do need to keep the reference in the blink layer.

PS2 was the correct patch.
