Replace the IPv6 header walking loop in pf_test_state_icmp() with

the common function pf_walk_header6().  For that, pf_walk_header6()
can now extract both the information wether it is a fragment and
the final protocol if it is the first fragment.  This allows to
match the icmp6 too big packet of a first fragment to the reassembled
packet's state.  This is neccesary if a refragmented fragment is
to big for the Path-MTU.
Note that pd.proto contains the real protocol number for the first
fragment and IPPROTO_FRAGMENT for later fragments.  pd.virtual_protocol
is set to PF_VPROTO_FRAGMENT for all fragments.
