LibOpenJPEG: restrict l_img_comp->prec to avoid undefined shift
The 38 value seems arbitrary, and the prec is used in OPJ_INT32 with 1 << (prec - 1). So limit it to be at most 31, and avoid undefined shifts. Bug: chromium:698498 Change-Id: I840f2e65231ac7847ed26bcaea36471a53be49e8 Reviewed-on: https://pdfium-review.googlesource.com/5173 Reviewed-by: Tom Sepez <tsepez@chromium.org> Commit-Queue: Nicolás Peña <npm@chromium.org>
