 - UDF fix to avoid memory corruption in face of corrupted format

 - Couple of ext2 fixes for better handling of fs corruption

 - Some more various code cleanups in UDF & ext2

  quota: Fix race of dquot_scan_active() with quota deactivation
  udf: fix partition descriptor append bookkeeping
  ext2: avoid drop_nlink() during unlink of zero-nlink inode in ext2_unlink()
  ext2: guard reservation window dump with EXT2FS_DEBUG
