Set avctx->coded_width/height to uncropped h264 sizes
avctx->width/height remain right/bottom cropped as previous behaviour.
Hardware decoders need to know the uncropped data to allocate surfaces
of correct height. Some hardware is picky and fails to decoder properly
if a surface larger than needed is used during decode, so just aligning
up is not enough.
