Fixed some confusion between the size of a logical block and the size of a
device block which was stopping symbolic links working.
cd9660_readdir was incorrectly casting a pointer to the d_namlen field of a
struct dirent to a (u_short*) which caused the directory entries "." and ".."
to read incorrectly.
