Kristof Provost 52b83a0618 pf: do not remove kifs that are referenced by rules 
Even if a kif doesn't have an ifp or if_group pointer we still can't delete it
if it's referenced by a rule. In other words: we must check rulerefs as well.

While we're here also teach pfi_kif_unref() not to remove kifs with flags.
