Verify Freeze/Export/Bounce polarity invert buffers

Browse Source 
When using bounce w/process, the initial bufferset can [wrongly] be
  buffers.set_count (track.max_processor_streams())
Since the polarity-processor is first in the chain, iterations
over all buffer that don't have a matching _current_gain[]
or _control[] leads to memory-corruption or segfault.
