Kristof Provost 48c29b118e pf: Always initialise pf_fragment.fr_flags ... When we allocate the struct pf_fragment in pf_fillup_fragment() we forgot to initialise the fr_flags field. As a result we sometimes mistakenly thought the fragment to not be a buffered fragment. This resulted in panics because we'd end up freeing the pf_fragment but not removing it from V_pf_fragqueue (believing it to be part of V_pf_cachequeue). The next time we iterated V_pf_fragqueue we'd use a freed object and panic. While here also fix a pf_fragment use after free in pf_normalize_ip(). pf_reassemble() frees the pf_fragment, so we can't use it any more.
