svn commit: r339491 - head/sys/dev/random

Log:
  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.
