ChangeLog, pass1.c, pass1b.c:
  pass1.c (pass1_get_blocks, pass1_read_inode, pass1_write_inode,
  	pass1_check_directory): Add a safety check to make sure
  	ctx->stashed_inode is non-zero.
  pass1b.c (pass1b): Use e2fsck_use_inode_shortcuts() to disable the
  	inode shortcut processing, instead of manually clearing only half of
  	the function pointers that needed to be NULL'ed out.  This caused
  	nasty bugs if the last inode in the filesystem needed dup block
  	processing.
  pass1b.c (clone_file_block): When cloning a directory's metadata
  	block, don't try to update the directory block list database, since
  	indirect blocks aren't stored in the database and the resulting error
  	will abort the file clone operation.
