Check if image width or height are zero before proceeding.
If the width of the CJBig2_Image is set to 0 then the stride_pixels will be zero and when we divide we'll get a floating point exception. If the width or height are zero then we can exit early without proceeding with the rest of the constructor. BUG=chromium:635008 Review-Url: https://codereview.chromium.org/2222843004
