[ros-diffs] [hbirr] 13278: - Check for some special file streams in VfatUpdateEntry.

[hbirr at svn.reactos.com]

- Check for some special file streams in VfatUpdateEntry. 
  W2K does open the volume for changing the date and time, 
  but the volume hasn't a parent fcb.  
- Fixed the directory index of a file for FATX.
