e2fsck: Fix directory with holes even when i_size is wrong
The old method for detecting directories with holes depended on i_size
being correct, even though the correct value of i_size hadn't been
calculated yet. Hence, a directory inode with holes and an i_size of
0 would require two e2fsck passes to fix completely.
The replacement method for determining whether or not
ext2fs_add_dir_block() should be called is more reliable, and reduces
the size of e2fsck and makes the code more readable as a bonus.
Thanks to Mikulas Patocka for providing a sample file system which
demonstrated this problem.
