    random(4): Correct a bare zero to the appropriate enum
    
    The convention for updating hc_destination[] is to index with a
    random_entropy_source.  Zero happens to match RANDOM_CACHED, which is
    correct for this source (early random data).  Spell the zero value as the
    enum name instead of the magic constant.
    
    No functional change.
    
    (cherry picked from commit 93d587e4d0442c7e702995b53668081240eefba2)
