    lc-dec: Disable low complexity decode mode when sharpness is 3

    Sharpness is tuned for perceptual quality improvements, whereas
    low complexity decode mode is tuned to reduce decoder complexity.
    Hence, this patch disables low complexity decode mode when the
    sharpness option is set to 3.
