data->size is initialised using grub_be_to_cpu32 (frec.size) in
grub_hfs_open. It looks fairly clearly incorrect for it to be converted
again; AFAICS that code will only work properly on little-endian CPUs.
This looks as if it ought to be better, although I'm not really in a
position to test it:
if (len > data->size)
len = data->size;
