pf: do not pass af to PFLOG_PACKET

Browse source 
Do not pass AF specific information to pf_test_rule() and PFLOG_PACKET()
because either the info is already available in struct pd or easy
to figure out.  Makes pf_test() and pf_test6() even more similar
(with the target to remove one of them in the near future).
