  Log:
  The primary mbuf cluster management code needs to be made MPSAFE since
  m_free() is now MPSAFE.  This involves using atomic_*() increment and
  decrement for the mbuf cluster ref count and using a serializer if there
  is a potential for a double-free (if the ref count is 2 or greater).  The
  common code path will tend not to need the serializer unless the interface
  is being tapped.
