    sbin/hammer: Make get_node() a wrapper over get_buffer_data()
    
    get_node() which is only used by hammer show/blockmap commands should
    be a wrapper over the existing get_buffer_data().
    
    It needs to do rel_buffer() if the given offset is out of range when
    *bufferp is non NULL. Adding this check makes this function equivalent
    of get_buffer_data() with 0 for isnew. isnew must be 0 because this
    function assumes and only works when the B-Tree node already exists.
    
    This doesn't change anything because hammer show/blockmap always give
    NULL for *bufferp, but it should still be changed.
