udf_load_logicalvolint() loads logical volume integrity descriptors. Since there can be multiple blocks with LVIDs, we verify the contents of only the last (prevailing) LVID found. However if we fail to load the last LVID (either due to IO error or because it's checksum fails to match), we never perform the verification of validity of the LVID we are going to use. If such LVID contains invalid data, we can hit out-of-bounds access or similar issues. Fix the problem by verifying each LVID we are potentially going to accept.
