Sabrina Dubroca 8e199dfd82 ipv6: call ipv6_proxy_select_ident instead of ipv6_select_ident in udp6_ufo_fragment
Matt Grant reported frequent crashes in ipv6_select_ident when
udp6_ufo_fragment is called from openvswitch on a skb that doesn't
have a dst_entry set.

ipv6_proxy_select_ident generates the frag_id without using the dst
associated with the skb.  This approach was suggested by Vladislav
Yasevich.

Fixes: 0508c07f5e0c ("ipv6: Select fragment id during UFO segmentation if not set.")
