gaoxingwang 1cd354fe1e net: ipv6: fix wrong start position when receive hop-by-hop fragment 
In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length.
But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header,
not the transport layer header or the first extension header.

This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced,
and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss.
We can use network header to offset and calculate the correct position to solve this problem.

Fixes: 9d9e937b1c (ipv6/netfilter: Discard first fragment not including all headers)
