udf: limit the maximum number of indirect extents in a row
commit b0918d9f476a8434b055e362b83fa4fd1d462c3f upstream.
udf_next_aext() just follows extent pointers while extents are marked as
indirect. This can loop forever for corrupted filesystem. Limit number
the of indirect extents we are willing to follow in a row.
