FX Le Bail d94c1f92bb ipv6: icmp6_send: fix Oops when pinging a not set up IPv6 peer on a sit tunnel
The patch 446fab5933 ("ipv6: enable anycast addresses
as source addresses in ICMPv6 error messages") causes an Oops when pinging a not
set up IPv6 peer on a sit tunnel.

The problem is that ipv6_anycast_destination() uses unconditionally skb_dst(skb),
which is NULL in this case.

The solution is to use instead the ipv6_chk_acast_addr_src() function.

Here are the steps to reproduce it:
modprobe sit
ip link add sit1 type sit remote 10.16.0.121 local 10.16.0.249
ip l s sit1 up
ip -6 a a dev sit1 2001🔢:123 remote 2001🔢:121
ping6 2001🔢:121
