[2.5] reiserfs: fix savelinks on bigendian arches

Hello!

This small patch fixes a savelinks problem on bigendian platforms, where savelinks were not working at all because of incorrect cpu->disk endianness conversion. Savelinks are used on reiserfs to remember "truncate" and "unlink" events so that if crash happens in the middle of truncate/unlink, we do not endup with lost or half truncated files.
The patch is against 2.6.0-test2
