[PATCH] Locking problems while EXT3FS_DEBUG on

I noticed some problems while running ext3 with the debug flag set on.
More precisely, I was unable to umount the filesystem.  Some investigation
took me to the patch that follows.

At a first glance , the lock/unlock I've taken out seems really not
necessary, as the main code (outside debug) does not lock the super.  The
only additional danger operations that debug code introduces seems to be
related to bitmap, but bitmap operations tends to be all atomic anyway.

I also took the opportunity to fix 2 spelling errors.
