ext2fs_dblist_iterate breaks its iteration loop if callback's return value
has set DBLIST_ABORT bit.
If ext2fs_dblist_iterate is called by ext2fs_dblist_dir_iterate,
the callback is db_dir_proc->ext2fs_process_dir_block, which returns BLOCK_ABORT
if something goes wrong.
BLOCK_ABORT is defined as 2, whereas DBLIST_ABORT is 1.
As result ext2fs_dblist_iterate does not break the iteration loop when
ext2fs_process_dir_block returns BLOCK_ABORT.
