URL: http://svnweb.freebsd.org/changeset/base/248144

Log:
  MFC r247906:
  
  The hashmask returned by hashinit() is a valid index in the returned hash array.
  Fix a siftr(4) potential memory leak and INVARIANTS triggered kernel panic in
  hashdestroy() by ensuring the last array index in the flow counter hash table is
  flushed of entries.
