fsck.c: Fix several bugs in dump mode.

- Don't abort if a  directory can't be created because it already exists.
- Use correct variable for the disk storage name column.
- If more than one table is to be dumped, use a directory for each table.
- Remove __a_unused for main()'s argc which _is_ being used.
