This has no sense, if there's any error, QImageReader::read checked in the previous condition will return false

Which format we're fixing for? If it's JPEG, I checked QJpegHandler code and it always re-allocates the image if either size or format isn't expected. And it never expects QImage::Format_ARGB32_Premultiplied. So if we're fixing for jpeg, this has no sense.
