    sbin/hammer: Remove unused READAHEAD flag
    
    - Cleanup get_buffer() by removing HAMMER_BUFINFO_READAHEAD since
      this flag does nothing, but taking care of negative 'isnew' for
      this flag makes things look complicated than it should.
    
    - For the else case, 'if (isnew >= 0)' is not necessary because it's
      always true from the way get_buffer() is recursively called via
      get_buffer_readahead() via get_buffer().
