How about if the MAD layer allocates a response MAD when a MAD is
received, and if the process_mad call doesn't actually generate a
response the MAD layer just stashed the response MAD away to use for
the next receive? This should keep the number of allocations within 1
of the number of responses actually generated, but save us from
tracking allocations between two layers.
