    barriers: Fix leak in meta_barrier_destroy
    
    meta_barrier_destroy is responsible for removing the extra
    reference added in meta_barrier_constructed.
    
    Unfortunately, it fails to do this because of a misplaced early
    return statement.
    
    This commit removes the spurious return.
