e2fsck: use ext2fs_write_dir_block3() instead of ext2fs_write_dir_block()

The use of ext2fs_write_dir_block() meant that attempts to fix
deleted/unused inodes in a directory would not be fixed for file
systems with 64-bit block numbers.  (And some random block with the
high 32-bits cleared would get corrupted.)

Fix a similar problem when expanding directories and when creating the
lost+found dirctory.
