 Log Message:
 Backport selected NPF fixes from the upstream (to be pulled up):
 
 - npf_conndb_lookup: protect the connection lookup with pserialize(9),
   instead of incorrectly assuming that the handler always runs at IPL_SOFNET.
   Should fix crashes reported on high load (PR/55182).
 
 - npf_config_destroy: handle partially initialized config; fixes crashes
   with some invalid configurations.
 
 - NAT policy creation / destruction: set the initial reference and do not
   wait for reference draining on destruction; destroy the policy on the
   last reference drop instead.  Fixes a lockup with the dynamic NAT rules.
 
 - npf_nat_{export,import}: fix a regression since dynamic NAT rules.
 
 - npfctl: fix a regression and restore the default group behaviour.
 
 - Add npf_cache_tcp() and validate the TCP data offset (from maxv@).
