PDP11, VAX: Fix DEUNA/DELUA receive descriptor message size indicator.

Browse source 
When packets arrive which require multiple receive buffers to deliver, the
full packet size is reported in the MLEN field of the final receive descriptor
used (the one with the ENF bit set).  Previously, correct behavior only
happened when the full packet fit into a single receive buffer.  This problem
was reported and the detail identified by Johnny Billquist.
