Test e2fsck' ability to deal with (a) corrupt descriptor block
checksum; (b) obviously bad journal block tid; and (c) corrupt journal
blocks. These should exercise the journal recovery infinite loop
bugfix earlier in this patchset.
This test also ensures that (with metadata_csum and journal_csum_v3)
journal replay continues past a corrupt journal block.
