    x86: upgrade: make code comment appear as log lines
    
    The comment content can be useful for readers of both the log and code
    
    Previously when dd command "records in/out" messages are not filtered
    like now with get_image_dd, it's not clear that these messages are for
    extracting boot sectors.  E.g.
    
    Before
    
      == upgrade: Reading partition table from bootdisk...
      37+26 records in
      37+26 records out
      == upgrade: Reading partition table from image...
    
    After
    
      == upgrade: Reading partition table from bootdisk...
      == upgrade: Extract boot sector from the image
      37+26 records in
      37+26 records out
      == upgrade: Reading partition table from image...
