[libdc] Core dump in dc1394_windows_capture_stop()

[<ke...@co...>]

Seen when trying out the current tip.  Proposed fix: 

  

In libdc1394/dc1394/windows/capture.c:363, replace 

  

    free (&craw->capture.frames); 

  

with 

  

    free (craw->capture.frames); 

  

For reference, the corresponding malloc is on line 255: 

  

    craw->capture.frames = 
        malloc (num_dma_buffers * sizeof (dc1394video_frame_t)); 


  

Thanks
