[PATCH] Ext2 flags shouldn't report "nogrpid"

[PATCH] Ext2 flags shouldn't report "nogrpid"

If I mount ext2 "rw", I want it to say "rw", not "rw,nogrpid".

I caught this writing an automated regression test script for the busybox
mount command.  The symptom is
  /dev/loop0 on /images/ext2.dir type ext2 (rw,nogrpid)
instead of:
  /dev/loop0 on /images/ext2.dir type ext2 (rw)

The behavior was introduced by git commit
8fc2751beb0941966d3a97b26544e8585e428c08.
