Generic node_rx_hdr struct contains data not used for done event, so this
pdu specific data is moved to node_rx_pdu to minimize memory usage for
MFIFO_done alloc.
This however calls for a considerable write-through replacing the generic
node_rx_hdr with node_rx_pdu when relevant and needed.

Make Data, ISO, BIS and CIS PDU structure's octet 3 vendor
specific.
This will allow vendors not supporting the octet 3 or
CTEInfo (8 bits) to save 1 octet in their PDU structures.
