fsck.gfs2: don't check newly created lost+found in pass2
    
    This patch checks whether lost+found was created during the run
    and if so, it skips pass2 directory checking for lost+found.
    The reason we need to do this is because when lost+found is created,
    it sets the directory linkage count to 1. If pass2 checks the
    directory, it will add it a second time because it checks it like
    every other normal directory. Therefore, the linkage counts get off.
    Plus, it's a waste of time to check it, since we just built it.
