Having to round like this looks like something the put_bits stuff could
maybe take care of. Not that that needs to hold this patch back of
course

I took a look at the surrounding code, and this patch looks OK. The
info->substream[i].num_dep_sub stuff modifying size looks a bit hacky
compared to computing the proper size
