---------------------------
mem: Only forward the non-writable flag if truly needed

This patch ensures a cache does not forward the non-writable flag from
a CPU-side request unless it has to. Thus, we avoid being overly
conservative and returning non-writable responses even when we know
that the response is the only writable copy in the system (the request
was sent out with NeedsWritable set).
