    swscale/ops: strip value range from garbage components
    
    Just removes the unnecessary value range after the WRITE, as a result of
    the previous change and the fact that we already skipped printing these for
    unused components.
    
     rgb24 -> bgr24:
       [ u8 XXXX -> +++X] SWS_OP_READ         : 3 elem(s) packed >> 0
         min: {0 0 0 _}, max: {255 255 255 _}
       [ u8 ...X -> +++X] SWS_OP_SWIZZLE      : 2103
         min: {0 0 0 _}, max: {255 255 255 _}
       [ u8 ...X -> XXXX] SWS_OP_WRITE        : 3 elem(s) packed >> 0
    -    min: {0 0 0 _}, max: {255 255 255 _}
         (X = unused, z = byteswapped, + = exact, 0 = zero)
