ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()
While investigating on why a synchronize_net() has been added recently
in ipv6_mc_down(), I found that igmp6_event_query() and igmp6_event_report()
might drop skbs in some cases.
Discussion about removing synchronize_net() from ipv6_mc_down()
will happen in a different thread.
Fixes: f185de28d9ae ("mld: add new workqueues for process mld events")
