e2fsck: collapse holes in extent-based directories

If we notice a hole in the block map of an extent-based directory,
offer to collapse the hole by decreasing the logical block # of the
extent.  This saves us from pass 3's inefficient strategy, which fills
the holes by mapping in a lot of empty directory blocks.
