Kristof Provost 5904868691 pf :Use counter(9) in pf tables.
The counters of pf tables are updated outside the rule lock. That means state
updates might overwrite each other. Furthermore allocation and
freeing of counters happens outside the lock as well.

Use counter(9) for the counters, and always allocate the counter table
element, so that the race condition cannot happen any more.
