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()).
