[Common] Disabled error log in case of Power special message

[Verification] Code compiles without errors.
  Below code works without any JS errors (special Power
    chromium message is ignored):
  tizen.power.request("SCREEN", "SCREEN_NORMAL");
  tizen.power.release("SCREEN");

  TCT passrate for Power module is 100% (A & M).
