net: rmnet_data: Support recycling frames to real device
For deaggregation, the real device receives a large linear skb and
passes it on to rmnet. rmnet creates new skbs from this large frame.
If the real device supports recycling, it does not need to allocate
the large skbs during packet reception and can instead reuse them.
