    sys/vfs/hammer2: Remove obsolete comments on blockset/blockref
    
    Apparently blockrefs are sorted with possible holes.
    1897c66ea31ca9d7b3fb03ba08889054bf36ef04 in 2013 changed how blockrefs
    within inode's blockset or indirect block are created/deleted.
    
    Inode has "ncopies" field, but redundancy isn't implemented.
    
    "blockrefs in a set can shortcut multiple levels of indirections"
    seems to have only existed in this comment.
