netfilter: ip6table_raw: fix table priority

Browse Source 
The order of the IPv6 raw table is currently reversed, that makes impossible
to use the NOTRACK target in IPv6: for example if someone enters

ip6tables -t raw -A PREROUTING -p tcp --dport 80 -j NOTRACK

and if we receive fragmented packets then the first fragment will be
untracked and thus skip nf_ct_frag6_gather (and conntrack), while all
subsequent fragments enter nf_ct_frag6_gather and reassembly will never
successfully be finished.
