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@).
