net: bridge: mcast: fix stale ipv6 hdr pointer when handling v6 query
[ Upstream commit 3b26a5d03d35d8f732d75951218983c0f7f68dff ]
We get a pointer to the ipv6 hdr in br_ip6_multicast_query but we may
call pskb_may_pull afterwards and end up using a stale pointer.
So use the header directly, it's just 1 place where it's needed.
Fixes: 08b202b67264 ("bridge br_multicast: IPv6 MLD support.")
