ipv6: mcast: remove one synchronize_net() barrier in ipv6_mc_down()
As discussed in the past (commit 2d3916f31891 ("ipv6: fix skb drops
in igmp6_event_query() and igmp6_event_report()")) I think the
synchronize_net() call in ipv6_mc_down() is not needed.
Under load, synchronize_net() can last between 200 usec and 5 ms.
KASAN seems to agree as well.
Fixes: f185de28d9ae ("mld: add new workqueues for process mld events")
