A v4 version of the patch.

- Dropped fixed_list and now removes corrupt bitmaps from the list via QSIMPLEQ_REMOVE
- We don't need to count the valid bitmaps, just know if the list was changed, so s/valid_bitmaps/bitmap_modified/
- update_ext_header_and_dir handles empty QSIMPLEQ and NULL the same way, so avoid the overhead of creating an empty QSIMPLEQ
- update_ext_header_and_dir modifies s->nb_bitmaps, so we can use that for # of corruptions fixed

Thanks
