>Description:
      after setting custom timeout values in pf.conf and reloading the config and then commenting out/deleting the lines with timeout settings, the setting remain set.
>How-To-Repeat:
1. set timeout value. e.g. by using following pf.conf line:
   set timeout tcp.closed 60
2. display timeout setting via 'pfctl -s timeout | grep tcp.closed'
3. reload pf configuration via 'pfctl -f /etc/pf.conf'
4. remove or comment out the line set in step 1
5. reload pf configuration
6. display tcp.closed timeout (as in step 2)

expected behavior:
after step 6, tcp.closed timeout should be set to default value
(as seen in step 2)
