e2fsck: mark sparse journal as invalid
For a filesystem that fails with:
journal_bmap: journal block not found at offset 7334 on loop0
JBD: bad block at offset 7334
e2fsck won't actually fix this; it will mark the fs as clean,
so it will mount, but it does not fix that block, and when the
journal reaches this point again it will fail again.
The following simple change to process_journal_block() might be
a little drastic; it will clear & recreate the journal inode if
it's sparse - i.e. if it gets block 0.
I suppose we could be more complicated and try to replay the journal
up to the error, but I'm not sure it's worth it since we're fscking
it anyway.
