net: ipv6: send pkttoobig immediately if orig frag size > mtu
If conntrack defragments incoming ipv6 frags it stores largest original
frag size in ip6cb and sets ->local_df.
We must thus first test the largest original frag size vs. mtu, and not
vice versa.
Without this patch PKTTOOBIG is still generated in ip6_fragment() later
in the stack, but
1) IPSTATS_MIB_INTOOBIGERRORS won't increment
2) packet did (needlessly) traverse netfilter postrouting hook.
