Fix the issue of using SilkFx crash on non-HDR-supported phone.

- ideally on non-HDR-supported phone, `Display#isHdrSdrRatioAvailable`
  should be false, while it's not the case in such phone now. The reason
  is hdrSdrRatio always gets updated. We should reject such update if
  there is no SdrHdrRatioMap loaded.
