ipv6: exthdrs: refresh nh after handling HAO option
ip6_parse_tlv() caches skb_network_header(skb) in nh while walking
IPv6 TLVs.
ipv6_dest_hao() may call pskb_expand_head() for a cloned skb, which can
move the skb head and invalidate the cached network header pointer.
Refresh nh after ipv6_dest_hao() returns so any trailing padding or TLVs
are parsed from the current skb head.
This matches the existing pattern used in ip6_parse_tlv() after helpers
that can modify skb header storage.
Fixes: a831f5bbc89a ("[IPV6] MIP6: Add inbound interface of home address option.")
