module_adapter: mark data buffers as cached 

Module adapter code uses struct input_stream_buffer and
struct output_stream_buffer to pass generic data to individual
modules for processing. Further, modules implementing the
.simple_copy option pass a cached pointer to struct audio_stream
which is already acquired at the generic code level. That means,
that in those cases .data contains cached memory aliases. This
patch marks the .data pointer as cached.
