eb2722609a11c992b55bf20dec1823b4118382c6 mem: Handle CMO responses in the snoop filter
Previously responses would either transfer the ownership of the line
or the actual data to the cache that send out the original request.
Cache clean operations are different since they bring neither data nor
ownership. When they are also invalidating the cache that send out the
original request will invalidate any existing copies. This patch
makes the snoop filter handle the cache clean responses accordingly.
