    vol: prevent salvage segfault for orphaned vnode with out-of-range parent
    
    While salvaging a RW volume, salvager may segfault if it encounters an
    orphaned directory with a parent vnode that does not exist.  For
    example, if the large vnode index contains a maximum vnode of 2901, any
    parent vnode encountered that is larger than 2901 will result in an
    out-of-bounds reference to our vnode essence array, leading to a
    segfault or undefined behavior.
    
    Modify the logic to check for out-of-bounds parent vnodes, and log them
    rather than segfaulting.
