resize2fs: fix crash when there is an ea block and no blocks to migrate

This fixes a bug introduced in 1.43 by commit fb47b94fffc: "resize2fs:
rewrite extent/dir/ea block checksums when migrating".  If there is an
extended attribute block and there are no blocks that need to migrate,
we will crash.

The bug was caused by a botched De Morgan's transformation.
