udf: cleanup directory offset handling
Position in directory returned by readdir is offset of directory entry divided by four (don't ask me why). Make this conversion only when reading f_pos from userspace / writing it there and internally work in bytes. It makes things more easily readable and also fixes a bug (we forgot to divide length of the entry by 4 when advancing f_pos in udf_add_entry()).
