  Log Message:
  -----------
  conntrack: Don't re-add cleaned 'conn' to expiry list.

When a 'conn' entry is cleaned up from an expiry list, we don't
want to put it back during an update.  Hence, we detect and block this.

  Log Message:
  -----------
  conntrack: Fix missed 'conn' lookup checks.

Whenever a 'conn' entry is removed or added, we need to reverify it's
existence status under lock protection.  There were some cases that
were missed, so fix them.

The new api incorporates the hash calculation which can be a
distraction.
