patch to fix the problem

This bug was discovered not long ago on gfs2's fsck.  
This patch is a RHEL4 port of that fix.
Comment 3 Robert Peterson 2007-05-04 13:48:11 UTC 
Fix was tested on RHEL4 system trin-12 and found to be correct by 
hand-damaging a bitmap with gfs_edit and fixing with gfs_fsck.
Fix was checked in to RHEL4 and STABLE branches of CVS.  Changing
status to modified.
