MFC rev. 182995
We can't implicitly trust the hook on NGQF_FN/NGQF_FN2 processing in
ng_apply_item(). There are possible (and I have got one) use-after-free
class panics because of it.
If hook is specified, require it to be valid at the apply time. The only
exceptions are the internal ng_con_part2(), ng_con_part3() and
ng_rmhook_part2() functions which are specially made to work with invalid
hooks.
