Vegard Nossum 20ea81dffe udf: limit the maximum number of indirect extents in a row ...

commit b0918d9f47 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.

[JK: Updated changelog, limit, style]
